text: "Nowadays, clinching is a widely used joining technique, where sheets are
joined by pure deformation to create an interlock without the need for auxiliary
parts. This leads to advantages such as reduced joining time and manufacturing\r\ncosts.
On the other hand, the joint strength solely relies on directed material deformation,
which renders an accurate material modelling essential to reliably predict the
joint forming. The formation of the joint locally involves large plastic strains
and possibly complex non-proportional loading paths, as typical of many metal
forming applications. Consequently, a finite plasticity formulation is utilised
incorporating a Chaboche–Rousselier kinematic hardening law to capture the Bauschinger
effect. Material parameters are identified from tension–compression tests on miniature
spec-\r\nimens for the dual-phase steel HCT590X. The resulting material model
is implemented in LS-Dyna to study the locally diverse loading paths and give
a quantitative statement on the importance of kinematic hardening for clinching.
It turns out that the Bauschinger effect mainly affects the springback of the
sheets and has a smaller effect on the joint forming itself."

text: "Force–displacement measurements and micrograph analyses are commonly used
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
images of the clinch point under loading conditions. In this paper, the potential
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: 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.
