text: "One of the major topics in the modern automotive industry is reducing emissions
and increasing the mileage\r\nrange. To tackle this challenge, on the one hand,
modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight
design offers various possibilities. Multi-Material Design (MMD) involves designing
car\r\nbodies that combine different materials that require joining. Given the
variety of materials, mechanical joining\r\nprocesses are preferred. Especially
the current development of the Giga/Mega-casting process concerning\r\naluminium
casting and the subsequent mechanical joining illustrates the challenges of this
material group. In car\r\nproduction, aluminium castings are mainly made from
aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient
ductility leads to crack initiation during mechanical joining. Cast parts are
therefore often\r\nused in areas of the car body that are exposed to high-pressure
loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing
capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure
through tailored solidification rates and a developed heat-treatment chain strategy
adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical,
and joining properties are used to develop a\r\nsolidification-joining correlation
for the SPR process across a range of Si contents and solidification rates. The\r\npurpose
is to develop the ability to produce suitable aluminium castings with sufficient
joinability, thereby\r\nimproving versatility."

text: The versatile self-pierce riveting (V-SPR) is a further development of semi-tubular
self-pierce riveting. V-SPR enables adaptation to changing boundary conditions,
such as a change in the material thickness combination, without varying the rivet
die combination due to increased punch actuation and the use of multi-range capable
rivets [1]. The inner punch first sets the rivet. The outer punch then forms the
rivet head to the respective sheet thickness. For this, the rivet requires a hard
shank and a ductile rivet head, which is achieved by an inductive local hardening
process [2]. Until now, the joint formation of rivets with graded hardness profile
has been challenging to estimate in the FEM simulation due to the inhomogeneous
material conditions in the rivet. In this study, a method capable of reproducing
the experimentally determined hardness levels of rivets in detail is shown. This
FE model enables the realistic modelling of the mechanical properties of the rivet
on the basis of the hardness profile in order to predict the correct deformation
processes and stresses during the riveting process. First, the detailed experimental
hardness mapping of the locally heat-treated rivets is transferred into the FE
model. The FEM material model can predict the local strength of the rivet based
on hardness by scaling the flow curves. To estimate the predictive capability
of the FEM model, the joint formation of rivets with different graded hardness
profiles is compared experimentally and simulative. Based on the validated model,
the influence of different rivet hardness profiles on the joint formation is analysed
numerically. By adapting the material model, a high level of correlation between
the experiment's joint formation and the simulation can be achieved.

text: "One of the most important strategies for reducing CO2 emissions in the mobility
sector is lightweight construction. In particular, the car body offers several
opportunities for weight reduction. Multi-material designs are increasingly being
applied to select the most suitable material for the respective load and ultimately
achieve synergy effects. For example, aluminium castings are used at the nodes
of a spaceframe body. Subsequently, these are joined with profiles to form the
bodyshell. To join different materials mechanical joining techniques, such as
semi-tubular self-piercing riveting, are deployed. According to the current state
of the art, cracks occur in the aluminium castings during the mechanical joining
process as a result of the high degree of deformation. Although the aluminium
casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent
castability. In particular, the ability to cast thin structural parts is enabled
by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis
study addresses the mechanical joining properties of the near eutectic aluminium
casting alloy AlSi12, depending on different microstructures. These are achieved
by annealing processes and modifying agents. Through an adapted heat treatment,
the previously lamellar morphology can be transformed into a globular morphology,
which leads to increased ductility and prevents the formation of cracks during
the self-piercing riveting (SPR). The joinability is investigated using different
die geometries, whereas the joint formation is analysed regarding crack initiation.
To evaluate the increased ductility, microstructural and mechanical tests are
performed and finally, a microstructure-joinability correlation is established."

text: The constantly increasing demand for climate protection and resource conservation
requires innovative and versatile joining processes that improve adaptability
to the joining task and robustness to enable flexible manufacturing on a production
line. Therefore, the versatile SPR (V-SPR) and tumbling SPR (T-SPR) were developed.
Using the example of a mixed material combination HCT590X+Z (t0 = 1.0 mm) / EN
AW-6014 T4 (t0 = 2.0 mm), these processes were examined and compared with regard
to the binding mechanisms form closure and force closure using micrographs, non-destructive
resistance measurements and destructive torsion tests. For this purpose, a new
sample geometry was defined, and the methods were adapted to the SPR process variants.

text: Conventional mechanical joining processes are typically rigid in their tool
systems and can only react to changing process and disturbance variables to a
limited extent. At the same time, various industries are increasingly trending
towards multi-material systems consisting of parts with varying geometric and
mechanical properties. Due to the varying properties, rigid mechanical joining
processes require sampling procedures and periodic changes of tool components
or auxiliary joining parts. Consequently, research is focusing on versatile mechanical
joining processes that allow increased control by modifying the process parameters.
Two processes based on self-piercing riveting can achieve a significant increase
in process influence possibilities through a multi-linear actuator as versatile
self-piercing riveting (V-SPR) and a tumbling superimposed actuator as tumbling
self-piercing riveting (T-SPR). Initial research into V-SPR has shown that this
process can be used to achieve a higher variation in overall package thickness
by adapting the rivet geometry and using multiple linear actuators. The T-SPR
process also enables increased material flow control by means of targeted compression
of the rivet using the tumbling actuator, thereby extending the range of joints
that can be manufactured. Based on these two processes, a combination of the two
mechanisms of action is to be developed.

text: Abstract. Mechanical joints are traditionally analyzed through destructive
micrograph analysis, which may compromise internal geometry and morphology, as
evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast,
industrial X-ray computed tomography (XCT) offers a non-destructive method for
component diagnosis, providing volumetric insights without damaging the sample
and enabling dimensional measurement. The DFG-funded Collaborative Research Center
TRR 285 is exploring XCT's application in assessing mechanical joinability across
various joining processes and materials, particularly in multi-material systems
like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material
compositions, leading to artifacts that complicate interface detection. This research
aims to validate XCT for joint investigations, yielding quantitative characteristics
that surpass those from traditional micrograph analysis.

text: Climate change has led to a large number of countries deciding to reduce carbon
dioxide (CO2) emissions significantly. As the mobility sector
is a major contributor to CO2, various strategies are being
pursued to achieve the climate targets set. An increasingly applied lightweight
design method is the use of multi-material constructions. To join these structures,
mechanical joining technologies such as self-pierce riveting are being used. As
a result of the currently rigid tool systems, which cannot react to changing boundary
conditions, a large number of rivet–die combinations is required to join the rising
number of materials as well as material thickness combinations. Thus, new, versatile
joining technologies are needed that can react to the described changes. The versatile
self-piercing riveting (V-SPR) process is one possible approach. In this process,
different material thicknesses can be joined by using a multi-range capable rivet
which is set by a joining system with extended actuator technology. In this study,
the V-SPR joining process is analysed numerically according to the influence of
the geometrical rivet parameters on the joints characteristics as well as the
resulting material flow. The investigations showed that the shank geometry has
a decisive influence on the expansion of the rivet. Furthermore, the rivet length
could be proven to be an influencing factor. By changing the head radii and the
protrusion height, the forming behaviour of the rivet head onto the punch-sided
joining part could be improved and thus the formation of air pockets was prevented.
Based on the numerical investigations, a novel rivet geometry was developed and
produced by machining. Subsequently, experimentally produced joints were analysed
according to their joint formation and load-bearing capacity.

text: The increasing significance of ecological responsibility, stricter political
regulations and economic objectives are driving innovation in research fields
such as lightweight construction. One of the most important popular methods is
the use of multi-material systems. Due to the different geometric and mechanical
properties of the various materials used, resource efficient applications and
utilizations are possible. Great challenges arise for the joining processes to
realize these multi-material systems, since conventional joining processes reach
their limits. In the field of mechanical joining processes, there are continuously
new approaches, such as superimposing the punch in a self-piercing riveting process
with a tumbling kinematic, to increase the number of adaptable process parameters
and enhance the process control. Through various preliminary tests, a good understanding
of the process has been developed, which allows to directly control the geometric
joint parameters by configuring the tumbling strategy. A major challenge, particularly
with regard to future industrial applications, is the process time, which is comparatively
high due to the tumbling kinematics. In the investigations, a reduction of approximately
90% of the process time is targeted by adapting the joining and tumbling strategy.
Therefore, the correlation of the traverse velocity and the tumbling velocity
are examined in a gradual series of experiments. To represent realistic applications,
the experiments are carried out with a dual-phase steel and a precipitation-hardening
aluminum alloy. For identifying the influence of the process parameters on the
joining process, a constant rivet–die combination is applied. Further, the examination
of force–displacement curves is conducted. Moreover, the determination of geometric
joint parameters is reliant upon macrographs to assess the influence of the joining
time on the geometric joint formation. The test results show that a significant
increase in joining speed with a resulting reduction in process time is feasible.
Although the joining properties are affected, reliable joining is possible. In
particular, the shaft thickness of the rivet is influenced by the varying proportion
of the tumbling process in the joining operation and increases with higher joining
speeds.

text: 'Increasing material costs, decreasing availability, and ever-higher demands
on environmental compatibility and complexity require new strategies in the development
and production of functional components. Consequently, a combined approach from
the areas of design, material science, and manufacturing is mandatory, in order
to meet the requirements. Reducing the number of parts, using lightweight materials
and applying hybrid components with a multimaterial mix are possible solutions.
Nevertheless, conventional joining operations like welding or riveting are reaching
their limits in terms of material utilization, load-bearing capacity as well as
versatility of the process. Thus, innovative and versatile joining by forming
operations and process combinations are focus of current research. In this context,
the innovative process of orbital forming had been investigated as a joining by
forming operation to manufacture load-adapted hybrid functional components. By
tilting of one tool component during the process, a radial material flow is generated,
allowing the crimping of the two joining partners. Nevertheless, the load-bearing
capacity in axial direction could be identified as limiting factor for a possible
application. Therefore, the aim of this investigation is the development of a
fundamental process understanding on the influence of a novel geometrical adaption
of the joint on the resulting load bearing capacity. The influence of varying
geometrical proportions of the joint on the quality is evaluated, considering
the form filling, the geometrical properties of the components as well as the
maximum transmittable axial load. As joining partners, the dual-phase steel DP600
and the aluminum alloy EN AW-5754 with a thickness of 2.0 mm are used. '

text: "Abstract\r\n An efficient lightweight construction method is
the combination of different materials in order to adapt the structure to the
applied load. To join these multi-material structures mechanical joining technologies
are applied. However, the rigid tooling systems cannot be adjusted to changing
boundary conditions which is why new, versatile joining technologies are required.
In the versatile self-piercing riveting (V-SPR) process presented in [1] different
material combination are joined by using a multi-range capable rivet. The rivet
head is formed onto the respective thickness of the joint by an outer punch. In
order to punch thru the upper sheet a great rivet hardness is required whereas
a lower hardness is required for the subsequent forming of the rivet head. To
achieve a combination of these requirements, this study investigates a local heat
treatment of the rivet. The aim is to determine the feasibility of such a heat
treatment as well as to investigate the influence on the joint formation."

text: Monitoring force-displacement or force-time curves is a widely used quality
control technique in the field of mechanical joining. For online monitoring of
self-piercing riveting, envelope curves are often used to define a tolerance zone
for the measured setting force. However, the measurement uncertainty is typically
not considered and the force curve of a joint can be wrongly rated as non-conform
due to measurement errors and noise. In this article, we present a method for
dynamical online filtering and uncertainty determination for noisy force curves
using two types of Bayesian filters. The methodology is based on a Bayesian probability
framework using a priori information for the process curve and sensor noise. To
investigate the general feasibility of the method, force measurements with different
noise levels are simulated and processed. The conformity is further assessed taking
the uncertainty of the filtered signal into account. The results show that the
Bayes filter technique is principally able to reduce noise for well-known characteristics
of the process curve and sensor noise. Advantages over common filtering techniques,
especially for experimental conditions with less known characteristics, are still
to be verified. The methodology could be used in future for closed-loop controls
to adapt process parameters dynamically.

text: Due to economic and ecological framework conditions, a resource-saving utilization
of raw materials and energy is becoming increasingly important in particular in
the mobility sector. For the reduction of moving masses and the resources consumed,
lightweight construction technologies are part of modern production processes
in vehicle manufacturing, for example in the form of multi-material systems. Challenging
in the manufacture of multi-material systems especially in view of changing supply
chains is the variety of materials and geometries that bring conventional joining
processes to their limits. Therefore, new processes are required, which can react
versatile to process and disturbance variables. A widely used industrial joining
process is semi-tubular self-piercing riveting, which is however a rigid process.
To increase the versatility, the two newly established processes multi-range self-piercing
riveting and tumbling self-piercing riveting are combined and the capabilities
for targeted material flow control are united. Therefore, an innovative two-stage
process based on the combination is introduced in this paper. The rivet is set
with the multi-range self-piercing riveting process with an overlap of the rivet
head and then formed by a tumbling process. Further, a specific adaptation of
the tumbling strategy is used to investigate the possibility of reducing cracks
in the rivet head. Thereby, different tumbling strategies are used and similar
geometric joint formations are achieved to compare the results.

text: Abstract. Increasing resource efficiency is a major challenge and
affects almost every aspect of social and economic life. The mobility sector in
particular is responsible for a large share of primary energy consumption and
is increasingly in the focus of public interest. One possibility to adress these
challenges is to reduce the vehicle weight by means of lightweight construction
technologies such as multi-material systems. These assemblies consist of workpieces
with different mechanical and geometrical properties, which poses a major challenge
for joining technology. Mechanical joining processes such as semi-tubular self-piercing
riveting are often used in the production of these assemblies, but due to their
process characteristics, they are rigid and can only react to changing process
variables to a limited extent. One way to increase the versatility of self-piercing
riveting is to superimpose a tumbling kinematics on the punch. During tumbling,
an angular offset of the punch axis to the tool axis is set and the contact area
between punch and workpiece is reduced. In this work, investigations were carried
out to determine how the tumbling strategy, consisting of the parameters tumbling
angle, tumbling onset and tumbling kinematics, affects the material flow of the
rivet element. For this purpose, experimental tests are conducted with the typical
materials of conventional multi-material systems and the geometric joint formations
are determined by means of macrographs.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

text: To achieve the climate objectives, various measures are taken to increase
the efficiency of raw materials and energies used. A sector with a large proportion
of the global consumption of resources is the mobility sector. To increase the
efficiency in this field, large efforts are made to reduce the weight of moving
masses. One approach is the use of multi-material systems, which utilises different
materials and their specific properties depending on the local requirements. Multi-material
systems consist often of materials which differ in strength and density, for example,
high-strength steels, aluminium alloys or polymers. Additionally, such a system
can utilise different geometries of the components to be joined, characterised
for example by varying sheet thicknesses. A central challenge of producing these
systems is the joining of the individual components. This requires robust joining
processes capable of covering the entire spectrum of possible variants and is
feasible for different physical properties of the materials. Since conventional
joining processes are rather rigid and have difficulty reacting to changing process
and disturbance variables, new joining processes are necessary. With the objective
of being able to react versatile to varying parameters, a process combination
consisting of a semi-tubular self-piercing riveting process and orbital forming
process with adjustable tumbling kinematic is introduced. Due to the process combination
of tumbling and self-piercing riveting, mutual influences of the two process components
are analysed in regard to material flow and process forces. Further, the investigations
show the influence of a varying tumbling angle on the joining process itself and
how the characteristic properties undercut, rivet head end position and residual
sheet thickness of the joint are affected. The material used for the joining partners
is an aluminium alloy EN AW-6014 typical for multi-material systems in the automotive
industry and the rivets are from type Rivset C produced by the Böllhoff company.

text: Pin extrusion is a common process to realise pin structures in different geometrical
dimensions for a subsequent joining operation. Nevertheless, the process of pin
extrusion offers process limits regarding sheet thinning as a consequence of the
punch penetration depth into the sheet. Thereby, cracks at the residual sheet
thickness can occur during strength tests, resulting in a failure of the complete
joint due to severe thinning. Therefore, measures have to be taken into account
to reduce the thinning. One possibility is the application of orbital formed tailored
blanks with a local material pre-distribution, which allows a higher sheet thickness
in the desired area. Within this contribution, the novel approach of a process
combination of orbital forming and pin extrusion is investigated. To reveal the
potential of a local material pre-distribution, conventional specimens are compared
with previously orbital formed components. Relevant parameters such as the residual
sheet thickness, the pin height as well as the average hardness values are compared.
The results show a significant positive influence of a local material pre-distribution
on the residual sheet thickness as well as the resulting pin height. Furthermore,
the strain hardening during orbital forming can be seen as an additional advantage.
To conclude the results, the process limits of conventional pin extrusion can
be expanded significantly by the application of specimens with a local material
pre-distribution.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

text: 'Clinching as a mechanical joining technique allows a fast and reliable joining
of metal sheets in large-scale production. An efficient design and dimensioning
of clinched joints requires a holistic understanding of the material, the joining
process and the resulting properties of the joint. In this paper, the process
chain for clinching metal sheets is described and experimental techniques are
proposed to analyze the process-microstructure-property relationships from the
sheet metal to the joined structure. At the example of clinching aluminum EN AW
6014, characterization methods are applied and discussed for the following characteristics:
the mechanical properties of the sheet materials, the tribological behavior in
the joining system, the joining process and the resulting material structure,
the load-bearing behavior of the joint, the damage and degradation as well as
the service life and crack growth behavior. The compilation of the characterization
methods gives an overview on the advantages and weaknesses of the methods and
the multiple interactions of material, process and properties during clinching.
In addition, the results of the analyses on EN AW 6014 can be applied for parameterization
and validation of simulations.'

text: Mechanical joining technologies are increasingly used in multi-material lightweight
constructions and offer opportunities to create versatile joining processes due
to their low heat input, robustness to metallurgical incompatibilities and various
process variants. They can be categorised into technologies which require an auxiliary
joining element, or do not require an auxiliary joining element. A typical example
for a mechanical joining process with auxiliary joining element is self-piercing
riveting. A wide range of processes exist which are not requiring an auxiliary
joining element. This allows both point-shaped (e.g., by clinching) and line-shaped
(e.g., friction stir welding) joints to be produced. In order to achieve versatile
processes, challenges exist in particular in the creation of intervention possibilities
in the process and the understanding and handling of materials that are difficult
to join, such as fiber reinforced plastics (FRP) or high-strength metals. In addition,
predictive capability is required, which in particular requires accurate process
simulation. Finally, the processes must be measured non-destructively in order
to generate control variables in the process or to investigate the cause-effect
relationship. This paper covers the state of the art in scientific research concerning
mechanical joining and discusses future challenges on the way to versatile mechanical
joining processes.
