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: The structural resolution describes the ability of a measuring device
to detect small structures on the surface of a component or test specimen by means
of a quantitative value. However, the structural resolution in the computer tomograph
depends on the object and must therefore be determined separately for each measurement
task. The previous approaches to structural resolution determination are only
related to test specimens. In this paper, less discrete approaches based on a
circular pattern are presented, which can be integrated into the measured component.
A voxel-based methodology as well as two surface-based methodologies are described.
The investigation results regarding the effect of the component position on the
structural resolution are obtained on the basis of real CT measurements. A comparison
is also completed with the well-known hourglass method. The results show that
the resolution depends on the object being measured, with similar values being
obtained for the same object using different methods.

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. The miniaturisation of components leads to new demands on measurement
systems. One of these is the resolution. As a volumetric analysis method and method
of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has
the ability to measure geometrical features and their corresponding dimensions
without destroying them and can therefore be used for quality assurance. However,
the concept of resolution is not trivial for XCT and has not yet been finally
clarified. In particular, the interface structural resolution, the detectability
of two surfaces facing each other after surface segmentation, faces a lack of
a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based
XCT investigations of a method to determine this type of resolution are presented
in this article using the geometry of a test specimen that contains several radially\r\narranged
holes of the same size. The borehole diameters correspond to the distance between
the holes to investigate the resolvability of surfaces and interfaces. The evaluation
is based on mean and extreme values of grey value\r\nprofiles between the individual
boreholes of the reconstructed volume. It is shown that the geometrical detectability
of the test specimen surface and interface can be extended by a reasonable choice
of the threshold value for\r\nsurface segmentation within a defined interval.
With regard to the resolving capability, a distinction is made between assured
detectability and possible detectability, as well as the threshold value used
when using the ISO50\r\nthreshold for surface segmentation and measurement chain
completion. "

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: Abstract. Force-displacement measurements and macrosections are commonly
used methods to validate numerical models of clinching processes. However, these
ex-situ methods often lead to springback of elastic deformations and crack-closing
after unloading. In contrast, the in-situ computed tomography (CT) can provide
three-dimensional images of the clinching point under loading conditions. So far,
the quantity of elastic springback that causes measuring deviations between in-
and ex-situ measurements is not determined. In this paper, a method is described
to quantitatively compare the results of in-situ CT, ex-situ CT and CT scans of
cut specimens, which are prepared for macrosectioning, among each other. The method
is applied to a single-lap shear test of two clinched aluminum sheets. Here, the
test is conducted to specific process steps, then the specimen is CT scanned in-situ
(during loading) and ex-situ (after unloading). Subsequently, the specimens are
cut for macrosectioning and CT scanned. Finally, the outer contours and the interfaces
of cross section images are determined by digital image analysis and the deviations
over the clinching point between ex- and in-situ methods are calculated.

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.

methods to validate numerical models of clinching processes. However, these methods
often lead to resetting of elastic deformations and crack-\r\nclosing after unloading.
In contrast, the in situ computed tomography (CT) can provide three-dimensional

of the in situ investigation of a clinching process as validation method is analyzed.
For the in situ testing, a tailored test set-up featuring a beryllium cylinder
for load-bearing and clinching tools made from ultra-high-strength titanium and
Si3N4 are used. In the experiments, the clinching of two aluminum sheets is interrupted
at specific process steps in order to perform the CT scans. It is shown that in
situ CT visualizes the inner geometry of the joint at high precision and that
this method is suitable to validate numerical models."

text: Resource-saving and sustainable production is becoming increasingly important
regarding social, political and economic aspects, thus making the use of lightweight-construction
technologies a current trend. For this reason, multi-material-systems made of
high-strength steel and aluminium as well as metal and fibre-reinforced plastics
gain in importance. However, different material properties, e.g. stiffness, thermal
expansion coefficients or chemical incompatibilities, are challenging for conventional
joining technologies. Joining by cold formed pin structures has shown to have
high potential for joining multi-material-systems. These pins can be joined either
by direct pin pressing into an unperforated joining partner or by caulking, where
the pins are inserted through a pre-punched joining partner and the pin head is
upset, resulting in a form-fit joint. Usually, cylindrical pins are used for joining.
However, non-rotationally symmetrical pin geometries offer the possibility of
introducing a predetermined breaking point or reinforcing a connection in the
principal force direction. In this work, cylindrical pins as well as non-rotationally
symmetrical pin geometries, such as polygonal and oval pin structures, are cold
extruded from the sheet metal plane of an HCT590X+Z dual phase steel and joined
in the next step with an EN AW-6014 aluminium using direct pin pressing. Since
the formation of an undercut has an crucial influence on the joint strength, the
investigations will be focused on the resulting joint geometry. In addition, the
effect of different pin heights will be examined to analyse the joint formation
at different levels of compression of the pin structures. Finally, the joints
are evaluated regarding their joint strength in tensile shear tests and cross
tension tests. Here the flow resistance of the geometry used as well as the pin
height and thus the strain hardening of the pin base during the extrusion of the
pins play a decisive role for the shear strength.

text: In this study, quasi-unidirectional continuous fiber reinforced thermoplastics
(CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and
polygonal pin structures which are directly pressed into the CFRT component after
local infrared heating. In comparison to already available studies, the unique
novelty is the use of non-rotational symmetric pin structures for the CFRT/metal
hybrid joining. Thus, a variation in the fiber orientation in the CFRT component
as well as a variation in the non-rotational symmetric pins’ orientation in relation
to the sample orientation is conducted. The created samples are consequently mechanically
tested via single lap shear experiments in a quasi-static state. Finally, the
failure behavior of the single lap shear samples is investigated with the help
of microscopic images and detailed photographs. In the single lap shear tests,
it could be shown that non-rotational symmetric pin structures lead to an increase
in maximum testing forces of up to 74% when compared to cylindrical pins. However,
when normalized to the pin foot print related joint strength, only one polygonal
pin variation showed increased joint strength in comparison to cylindrical pin
structures. The investigation of the failure behavior showed two distinct failure
modes. The first failure mode was failure of the CFRT component due to an exceedance
of the maximum bearing strength of the pin-hole leading to significant damage
in the CFRT component. The second failure mode was pin-deflection due to the applied
testing load and a subsequent pin extraction from the CFRT component resulting
in significantly less visible damage in the CFRT component. Generally, CFRT failure
is more likely with a fiber orientation of 0° in relation to the load direction
while pin extraction typically occurs with a fiber orientation of 90°. It is assumed
that for future investigations, pin structures with an undercutting shape that
creates an interlocking joint could counteract the tendency for pin-extraction
and consequently lead to increased maximum joint strengths.
