text: Similar to bulk metal forming, clinch joining is characterised by
large plastic deformations and a variety of different 3D stress states, including
severe compression. However, inherent to plastic forming is the nucleation and
growth of defects, whose detrimental effects on the material behaviour can be
described by continuum damage models and eventually lead to material failure.
As the damage evolution strongly depends on the stress state, a stress-state-dependent
model is utilised to correctly track the accumulation. To formulate and parameterise
this model, besides classical experiments, so-called modified punch tests are
also integrated herein to enhance the calibration of the failure model by capturing
a larger range of stress states and metal-forming-specific loading conditions.
Moreover, when highly ductile materials are considered, such as the dual-phase
steel HCT590X and the aluminium alloy EN AW-6014 T4 investigated here, strong
necking and localisation might occur prior to fracture. This can alter the stress
state and affect the actual strain at failure. This influence is captured by coupling
plasticity and damage to incorporate the damage-induced softening effect. Its
relative importance is shown by conducting inverse parameter identifications to
determine damage and failure parameters for both mentioned ductile metals based
on up to 12 different experiments.

text: ' Clinching is a mechanical joining technology, in which a mainly
form-fit joint is created by means of local cold forming. To characterize the
load-bearing behavior of such joints, they are typically analyzed destructively,
for example by tensile-shear tests in combination with metallographic sections.
However, both the initiation and progress of failure can only be described to
a limited extent by this method. Furthermore, these tests allow only limited conclusions
about clinch points under in-service loading. More purposefully, clinch points
can be analyzed nondestructively by combining in-situ computed tomography (CT)
and transient dynamic analysis (TDA). The TDA continuously measures the dynamic
behavior of the specimen and indicates failure events like crack initiation, which
then can be evaluated thoroughly by stopping the test and performing a CT scan.
To qualify the TDA for this task, it is necessary to link the observed damage
behavior with specific dynamic characteristics. In this work, the complementation
of in-situ CT and TDA is investigated by testing a clinched single-lap tensile-shear
specimen made of aluminum. The testing procedure is stepwise: at certain displacement
levels, the specimen is investigated by in-situ CT and TDA. While the in-situ
CT provides the location, extent, and development of the failure phenomena, the
TDA uses this information to evaluate the dynamic signal and detect relevant frequency
ranges, which indicate damage events. The results demonstrate, that failure initiation
and progression can be analyzed efficiently by combining both measuring systems.
The TDA reliably detects relevant signal changes in the monitored frequency band.
By means of in-situ computed tomography, the corresponding failure phenomena can
be described in detail, enhancing the understanding of the load-bearing and deformation
behavior of clinch points. The concatenation of characteristic signal changes
and observed failure phenomena can henceforth be transferred to analyze complex
structures during operation nondestructively by TDA. '

text: Lightweight design by using low-density and load-adapted materials
can reduce the weight of vehicles and the emissions generated during operation.
However, the usage of different materials requires innovative joining technologies
with increased versatility. In this investigation, the focus is on describing
and characterising the failure behaviour of connections manufactured by an innovative
thermomechanical joining process with adaptable auxiliary joining elements in
single-lap tensile-shear tests. In order to analyse the failure development in
detail, the specimens are investigated using in-situ computed tomography (in-situ
CT). Here, the tensile-shear test is interrupted at points of interest and CT
scans are conducted under load. In addition, the interrupted in-situ testing procedure
is validated by comparing the loading behaviour with conventional continuous tensile-shear
tests. The results of the in-situ investigations of joints with varying material
combinations clearly describe the cause of failure, allowing conclusions towards
an improved joint design.

text: Abstract. In lightweight constructions, clinching represents a cost-effective
solution, in which joints are produced by local cold forming of the joining parts.
Clinching phenomena are typically evaluated using destructive testing methods.
While these methods influence the clinch point’s state, in-situ computed tomography
(in-situ CT) is able to explore the clinching process with a specimen under load.
Here, the path-controlled clinching process is interrupted at certain displacement
levels and the specimen is scanned by CT while remaining in a stationary state.
These interruptions are always accompanied by settling effects reducing the reaction
force. Therefore, in this work, the influence of these interruptions on the force-displacement
behavior during clinching and on the final clinch point’s geometric properties
is investigated.

text: 'AbstractMechanical clinching is a frequently
used joining method for technical components. These joints are usually weak spots.
Here, corrosion and fatigue are decisive influencing factors for the assessment
of the service life of such joints. Corrosion generally leads to material deterioration
and thus to premature failure of the joints. Under certain circumstances, however,
corrosion can lead to an increased fatigue life. While this effect has not yet
been fully understood, the present work provides a possible explanation and a
modeling approach to predict the fatigue life of precorroded clinched joints.
The increased fatigue life is observed when the clinched components are briefly
(up to 3 weeks) exposed to a salt spray environment. During this time, a small
layer of corrosion products protrudes from the metal surface and fills the gaps
between the joined sheets. Due to the increased contact area, the mechanical stress
in the joint decreases, resulting in an improved fatigue performance. Although
there are a variety of corrosion phenomena, for example, pitting, intergranular,
and transgranular corrosion as well as galvanic corrosion, experimental studies
indicate that galvanic corrosion is the main contributor of this effect. In the
present work, a coupled electro‐chemo‐mechanical corrosion model is presented
and applied to two test cases. Case I: corrosion products growth, and Case II:
corrosion products growth and mechanical loading.'

text: A numerical modelling strategy for the direct pin pressing process
of metallic pins into continuous fibre-reinforced thermoplastic organosheets is
developed. The joining process is performed above the thermoplast’s melting temperature,
altering the initial material structure of the composite by fibre rearrangement,
which in turn influences the load-bearing capacity of the joint. Therefore, the
modelling strategy aims at predicting the resultant material structure after pin
pressing. The modelling approach considers both the textile architecture and the
process parameters (temperature, tool velocity). A sub-meso modelling framework
for the fibres based on a multi-filament approach is used. The interaction between
fibres and the thermoplastic melt, as well as the matrix flow, is modelled using
the Arbitrary Lagrangian Eulerian method. This allows for the prediction of matrix-rich
zones and fibre rearrangement around the pin. The promising results show a good
agreement of the resultant material structure in terms of compaction and fibre
volume content around the pressed pin. Characteristic parameters show an underestimation
of the laminate thickness below the pin. Moreover, an evaluation method for evaluating
the orientation changes of the virtual multi-filaments is developed and presented
to observe and assess fibre rearrangement and fibre volume content in detail during
the numerical process simulation. It can be seen that only fibres around the pin
are displaced and not in the whole molten area. Furthermore, it can be observed
in detail that the initial position of the fibres in relation to the pin determines
whether the fibres are displaced in the in-plane or out-of-plane direction.

text: 'Fiber reinforced plastics (FRP) exhibit strongly non-linear deformation behavior.
To capture this in simulations, intricate models with a variety of parameters
are typically used. The identification of values for such parameters is highly
challenging and requires in depth understanding of the model itself. Machine learning
(ML) is a promising approach for alleviating this challenge by directly predicting
parameters based on experimental results. So far, this works mostly for purely
artificial data. In this work, two approaches to generalize to experimental data
are investigated: a sequential approach, leveraging understanding of the constitutive
model and a direct, purely data driven approach. This is exemplary carried out
for a highly non-linear strain rate dependent constitutive model for the shear
behavior of FRP.The sequential model is found to work better on both artificial
and experimental data. It is capable of extracting well suited parameters from
the artificial data under realistic conditions. For the experimental data, the
model performance depends on the composition of the experimental curves, varying
between excellently suiting and reasonable predictions. Taking the expert knowledge
into account for ML-model training led to far better results than the purely data
driven approach. Robustifying the model predictions on experimental data promises
further improvement. '

text: Abstract. Traditionally, joints are cylindrical and rotationally symmetric.
In the present study, non-rotationally symmetric joints are used for joining steel
and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also
analyzes the impact of non-rotational symmetric joint rotation on the load-bearing
capacity. Single lap joint specimens were fabricated using the In-Mold assembly
technique for joining steel sheets with GMT. Tensile shear tests were performed
on different orientations of the joint geometry, and it was observed that changing
the joint orientation influences the load-bearing capacity. The joints are constitutively
modeled using beam elements and the influence of joint rotation on load distribution
is examined through a static simulation study.

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: This study focuses on the phenomenological change in material strength caused
by a specific heat treatment and the subsequent analysis of the influence on the
clinching process and the resulting joint properties. For this purpose, three
series of tests were performed. In the first series of tests, the influence of
heat treatment up to 340 °C on the mechanical properties of an age-hardenable
AlMgSi alloy was investigated. Holding time and temperature were varied and the
material strength was evaluated by tensile and hardness tests. Two strength-increasing
and two strength-reducing heat treatment parameters were identified. In the second
series of tests, selected heat treatment parameters were applied to a larger number
of specimens and the joint strength was investigated by shear and head tensile
tests. In the shear tensile test, mainly the properties of the punch-side material
have an influence on the resulting joint strength. A change in strength of the
die-side material can be neglected. In contrast, the properties of both sheets
are important in the head tensile test. The strength of the joint will only increase
if the strength of both sheets is increased. In general, a strength increasing
heat treatment resulted in higher joint strength. In the third series of tests,
the factor of punch displacement was considered, which was demonstrated to directly
influence the formation of the clinched joint geometry.

text: Abstract. Reducing the weight of vehicles can significantly lower
the energy or fuel consumed and thus the emissions during operation. One possibility
to assess this is the use of a property adapted multi-material systems containing
high strength steel, light metals like aluminium or magnesium and fibre reinforced
plastics. While expanding the number of materials used new challenges arise for
the production and furthermore the joining technology to manufacture the vehicle
made of the multi-material systems. One approach to overcome these challenges
is to use innovative and adaptable joining techniques which allows the manufacturing
of joints of different material combinations. Extensive research activities on
the two stage thermo-mechanical joining process with adaptable joining elements
was able to demonstrate the great potentials in terms of joining dissimilar materials
with good strength. The previously kinematic and path-based fabrication of auxiliary
joining elements is modified in this publication to a form-based approach with
a perspective of establishing an efficient process chain using easily and cheaply
available rods. Based on the new approach to produce the auxiliary joining elements,
it can be demonstrated that a reproducible production of the geometry is possible
for the investigated steel as well as aluminium material.
