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: 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.

text: The application of the mechanical joining process clinching enables the joining
of sheet metals with a wide range of material-thickness configurations, which
is of interest in lightweight construction of multi-material structures. Each
material-thickness combination results in a joint with its own property profile
that is affected differently by variations. Manufacturing process-related effects
from preforming steps influence the geometric shape of a clinched joint as well
as its load-bearing capacity. During the clinching process high degrees of plastic
strain, increased temperatures and high strain rates occur. In this context, a
3D numerical model was developed which can represent the material-specific behaviour
during the process chain steps sheet metal forming, joining, and loading phase
in order to achieve a high predictive accuracy of the simulation. Besides to the
investigation of the prediction accuracy, the extent of the influence of individual
modelling aspects such as temperature and strain rate dependency is examined.

text: Clinching as a mechanical joining process has become established
in many areas of car body. In order to predict relevant properties of clinched
joints and to ensure the reliability of the process, it is numerically simulated
during the product development process. The prediction accuracy of the simulated
process depends on the implemented friction model. Therefore, a new method for
determining friction coefficients in sheet metal materials was developed and tested.
The aim of this study is the numerical investigation of this experimental method
by means of FE simulation. The experimental setup is modelled in a 3D numerical
simulation taking into account the process parameters varying in the experiment,
such as geometric properties, contact pressure and contact velocity. Furthermore,
the contact description of the model is calibrated via the experimentally determined
friction coefficients according to clinch-relevant parameter space. It is shown
that the assumptions made in the determination of the experimental data in preliminary
work are valid. In addition, it is investigated to what extent the standard Coulomb
friction model in the FEM can reproduce the results of the experimental method.

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.

- lang: eng
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: AbstractIn order to reduce fuel consumption
and thus pollutant emissions, the automotive industry is increasingly developing
lightweight construction concepts that are accompanied by an increasing usage
of aluminum materials. Due to poor weldability of aluminum in combination with
other materials, mechanical joining methods such as clinching were developed and
established in series production. In order to predict the relevant characteristics
of clinched joints and to ensure the reliability of the process, it is simulated
numerically during product development processes. In this regard, the predictive
accuracy of the simulated process highly depends on the implemented friction model.
In particular, the frictional behavior between the sheet metals as well as between
the sheet metal and clinching tools has a significant impact on the geometrical
formation of the clinched joint. No testing methods exist that can sufficiently
investigate the frictional behavior in sheet materials, especially under high
interface pressures, different relative velocities, and long friction paths, while
allowing a decoupled consideration of the test parameters. This paper describes
the development of further testing concepts based on a proven tribo-torsion test
method for determining friction coefficients between sheet metal materials for
the simulation of clinching processes. For this purpose, the correlation of interface
pressure and the relative velocity between aluminum and steel sheet material in
clinching processes is investigated using numerical simulation. Based on these
findings, the developed concepts focus on determining friction coefficients at
interface pressures of the above materials, yield stress, as well as the reproduction
of the occurring friction conditions between sheet metal materials and tool surfaces
in clinching processes using tool substitutes. Furthermore, wear investigations
between sheet metal material and tool surface were carried out in the friction
tests with subsequent EDX analyses of the frictioned tool surfaces. The developed
method also allows an optical deformation measurement of the sheet metal material
specimen by means of digital image correlation (DIC). Based on a methodological
approach, the test setups and the test systems used are explained, and the functionality
of the concepts is proven by experimental tests using different sheet metal materials.

text: The predictive quality of numerical simulations for mechanical joining processes
depends on the implemented material model, especially regarding the plasticity
of the joining parts. Therefore, experimental material characterization processes
are conducted to determine the material properties of sheet metal and generate
flow curves. In this regard, there are a number of procedures which are accompanied
by varying experimental efforts. This paper presents various methods of determining
flow curves for HCT590X as well as EN AW-6014, including varying specimen geometries
and diverse hardening laws for extrapolation procedures. The flow curves thus
generated are compared considering the variety of plastic strains occurring in
mechanical joining processes. The material data generated are implemented in simulation
models for the joining technologies, clinching and self-piercing riveting. The
influence of the varied methods on the predictive accuracy of the simulation model
is analysed. The evaluation of the differing flow curves is achieved by comparing
the geometric formation of the joints and the required joining forces of the processes
with experimentally investigated joints.
