text: Abstract. In the development of advanced lightweight automotive solutions,
self-piercing riveting (SPR) offers the possibility of joining multi-material
structures to fulfil a wide variety of requirements. With regard to the entire
process chain, production-related pre-deformations of the parts to be joined can
influence the geometric shape and load capacity of SPR joints. Various studies
have investigated the influence of pre-stretched sheet materials, in the sense
of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching
sheet metals on the formation of their geometrical characteristics and the shear-tensile
strength of SPR processes was observed [1]. Pre-rolled semi-finished products
are also joined together in mixed material automotive structures, e.g. tailor
rolled blanks. This work aims to investigate the influence of pre-rolled joining
parts on the geometric formation and load-carrying capacity of SPR joints. For
this purpose, sheets of metal are cold-formed using a rolling process to induce
a defined strain-hardening state in the material and then joined in various combinations.
As the degree of deformation increases, the rolling of samples can lead to minimal
accumulation of damage in the sheet materials, which can influence the joint behaviour.
The rolling process, as well as the subsequent joining process, are also investigated
by FEM. The influence of pre-rolled semi-finished products on the strength of
the SPR joints is investigated.

text: The present study is an experimental analysis of the influence of pre-forming
on the failure behaviour of clinched specimens under quasi-static and cyclic loading
conditions. In this context, the geometric formation of the clinched joints is
taken into account, with regard to the loading behaviour. The study also includes
a comparison of the failure behaviour of quasi-static and cyclic tested specimen.
Testing is done on non-pre-deformed and pre-deformed specimens. For this purpose,
experimental investigations are carried out on two material combinations consisting
of HCT590X steel sheet and EN AW-6014 T4 aluminium sheet. The focus is on the
fatigue analysis of the clinched joints. The aim is to identify the failure modes
under cyclic loading and the crack formation with regard to forming operations
prior to the joining process. The investigations show that the cyclic load-bearing
behaviour of the HCT590X joints is reduced by introducing a plastic pre-deformation
of the to be joined parts.

text: This study focuses on damage modeling across different mechanical joining
processes within a process chain, specifically using clinching and self-pierce
riveting (SPR). The aim is to apply a comprehensive model that captures the damage
mechanisms and interactions in these technologies, optimizing them for enhanced
performance and durability of aluminum joints. A GISSMO damage model was utilized,
based on the stress states occurring during the joining process and a newly introduced
damage testing method. This model was applied to both clinching and SPR processes.
A detailed analysis of the stress states provided insights into their effect on
the material. By incorporating these insights into the GISSMO model, improved
accuracy in damage prediction was achieved. The model's application to clinching
and SPR demonstrated its effectiveness in optimizing aluminum joint performance
and durability, ensuring that the processes can be finely tuned to minimize damage
and enhance joint quality.

text: Abstract. Structures made of aluminum die casting are being used in
increasing quantities as well as component sizes for various applications. Due
to the size of the components, heat treatment of the cast parts following the
casting process is omitted in order to meet dimensional accuracy requirements
and reduce production costs. From such an approach, challenges arise with regard
to the mechanical joining of these aluminum die-cast structures. On one hand,
the absence of heat treatment results in a general decrease in ductility. On the
other hand, the increasing size of the components introduces process-related tolerances
regarding the quality of the casting, including the presence of air or gas inclusions,
and significant variations in ductility within the component. These factors present
challenges for mechanical joining technologies, such as the potential risk of
crack-related defects during the joining process. For the robust mechanical joining
of such materials, the development and validation of suitable joining strategies
for aluminum die cast components is presented in this paper. A preparatory step
involving localized heat treatment in the joining area is implemented to enhance
the suitability of the casting material for mechanical joining. The objective
is to generate an improved ductility state in the aluminum die casting material,
enabling crack-free joining through self-pierce riveting. Additionally, the formability
of the aluminum die casting material is characterized using a specially developed
ductility testing method. This allows the prediction of potential crack-related
defects during mechanical joining. The methods described are developed using the
AlSi10MnMg material in its as-cast state and applied to the self-pierce riveting
process.

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: Abstract. The application of the mechanical joining process clinching
allows the assembly of different sheet metal materials with a wide range of material
thickness configurations, which is of interest for lightweight multi-material
structures. In order to be able to predict the clinched joint properties as a
function of the individual manufacturing steps, current studies focus on numerical
modeling of the entire clinching process chain. It is essential to be able to
take into account the influence of the joining process-induced damage on the load-bearing
capacity of the joint during the loading phase. This study presents a numerical
damage accumulation in the clinching process based on an implemented Hosford-Coulomb
failure model using a 3D clinching process model applied on the aluminum alloy
EN AW-6014 in temper T4. A correspondence of the experimentally determined failure
location with the element of the highest numerically determined damage accumulation
is shown. Moreover, the experimentally determined failure behavior is predicted
to be in agreement in the numerical loading simulation with transferred pre-damage
from the process simulation.

text: Abstract. In the numerical simulation of mechanical joining technologies
such as clinching, the material modeling of the joining parts is of major importance.
This includes modeling the damage and failure behavior of the materials in accordance
with varying occurring stress states. This paper presents a calibration method
of three different fracture models. The calibration of the models is done by use
of experimental data from a modified punch test, tensile test and bulge test in
order to map the occurring stress states from clinching processes and to precisely
model the resulting failure behavior. Experimental investigations were carried
out for an aluminum alloy EN AW-6014 in temper T4 and compared with the simulative
results generated in LS-DYNA. The comparison of force-displacement curves and
failure initiation shows that the Hosford–Coulomb model predicts the failure behavior
for the material used and the tests applied with the best accuracy.

text: Background. Clinching is a conventional cold forming process in which two
or more sheets can be joined without auxiliary parts. A pre-forming of the parts
to be joined, which is introduced by previous manufacturing steps, has an influence
on the joining result. When considering the suitability for joining with regard
to the formability of the materials, the influence of the preforming steps must
be taken into account. The influences of strain hardening and sheet thickness
on the joining properties must be investigated. In this context, a Finite Element
Method (FEM) based metamodel analysis of the clinching process was carried out
in [1] to investigate the robustness of the clinching process with respect to
the different material pre-strains. In [2], the method was extended to the load
bearing simulation.Procedure. The metamodel from preliminary work based on various
FE models, which predicts the load-bearing capacity of a clinched joint influenced
by pre-straining, is compared here with experimental data and the accuracy of
the metamodel prediction is discussed. For this purpose an experimental procedure
was further develop which allows the preforming of metal sheets from which joining
specimens can be separated with a certain degree of unidirectional deformation.
In the study, the procedure for preparing the joint specimens and the results
of the loading tests are presented. Different possible relevant pre-strain combinations
are investigated and compared with the simulation results, to validate the FE
models and choose suitable metamodel.

text: In many manufacturing areas, multi-material designs are implemented
in which individual components are joined together to form complex structures
with numerous joints. For example, in the automotive sector, cast components are
used at the junctions of the body and joined with different types of sheet metal
and extruded profiles. To be able to join structures consisting of different materials,
alternative joining technologies have emerged in recent years. This includes clinching,
which allows assembling of two or more thin sheet metal and casting parts by solely
cold forming the material. Clinching the brittle and usually less ductile cast
aluminium alloys remains a challenge because the brittle character of the cast
aluminium alloys can cause cracks during the forming of the clinched joint. In
this study, the influence of the heat treatment time of an aluminium casting alloy
AlSi9 on the joinability in the clinching process is investigated. Specific heat
treatment of the naturally hard AlSi9 leads to a modification of the eutectic
microstructure, which can increase ductility. Based on this, it will be examined
if specific clinching die geometries can be used, which achieve an optimized geometrical
formation of the clinched joint. The load-bearing capacities of the clinched joints
are determined and compared by shear tensile and head tensile tests. Furthermore,
the joints are examined microscopically to investigate the influence of the heat
treatment on the failure behaviour during the load-bearing tests as well as crack
initiation within the joining process.

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: Many mechanical material properties show a dependence on the strain
rate, e.g. yield stress or elongation at fracture. The quantitative description
of the material behavior under dynamic loading is of major importance for the
evaluation of crash safety. This is carried out using numerical methods and requires
characteristic values for the materials used. For the standardized determination
of dynamic characteristic values in sheet metal materials, tensile tests performed
according to the guideline from [1]. A particular challenge in dynamic tensile
tests is the force measurement during the test. For this purpose, strain gauges
are attached on each specimen, wired to the measuring equipment and calibrated.
This is a common way to determine a force signal that is as low in vibration and
as free of bending moments as possible. The preparation effort for the used strain
gauges are enormous. For these reasons, an optical method to determine the force
by strain measurement using DIC is presented. The experiments are carried out
on a high speed tensile testing system. In combioantion with a 3D DIC high speed
system for optical strain measurement. The elastic deformation of the specimen
in the dynamometric section is measured using strain gauges and the optical method.
The measured signals are then compared to validate the presented method. The investigations
are conducted using the dual phase steel material HCT590X and the aluminum material
EN AW-6014 T4. Strain rates of up to 240 s-1 are investigated.
