text: This paper focuses on the failure behavior of clinched specimens with various
stiffnesses under shear tensile loading. The primary objective is to assess the
influence of the specimen stiffness with an arrangement of clinched joints. The
specimen stiffness depends on several variables. In addition to the material selection,
the specific choice of geometry and the design of the clinched joints must also
be taken into account. A number of experiments was conducted to investigate the
failure behavior of specimens with an arrangement of three clinched joints under
shear tensile loading. These configurations were subjected to shear tensile tests,
with force displacement curves recorded for each specimen to provide a detailed
characterization of their structural response. The stiffness is modified by altering
the specimen width, which has marginal impact on the maximum force. The experimental
findings indicate that reducing the specimen stiffness results in a shift in the
type of stress, with the failure behavior becoming increasingly influenced by
bending stress. These results offer important insights for the design of clinched
joint assemblies, indicating that it is feasible to achieve the desired properties
by changing the specimen stiffness.

text: This paper focuses on the failure behavior of specimens with various configurations
of clinched joints under shear tensile loading. The primary objective is to assess
the influence of the joining direction and the spatial arrangement of clinched
joints on their mechanical performance. A number of experiments was conducted,
focusing on three clinched joints arranged in different configurations, each varying
in terms of joining direction and spacing. These configurations were subjected
to shear tensile tests, with force-displacement curves recorded for each sample
to provide a detailed characterization of their structural response. The experimental
findings indicate that the specific arrangement of the clinched joints, in terms
of joining direction, has a marginal impact on the overall failure behavior. This
suggests that intricate modifications to the joining direction are unnecessary
to achieve improved mechanical performance in such applications. These results
offer valuable insights for the design of clinched joint assemblies, indicating
that simplified joining strategies may suffice without compromising structural
integrity under shear loading.

text: This paper examines the impact of a rotationally superimposed punch stroke
on the binding mechanisms of clinched joints of aluminum sheets. As part of the
development of a method for ensuring the versatility of clinching, an additional
rotational movement of the punch was introduced as a control variable to influence
friction in the mechanical joining process. The effect of rotational superimposition
on the force-displacement curve of the clinching processes was investigated using
four test variants with different kinematics. The primary objective was to evaluate
the binding mechanisms that maintain the integrity of the clinched joint. To evaluate
the force closure of the resulting joint, two testing methods were employed throughout
the course of the research, non-destructive resistance measurement using four-wire
sensing method and destructive torsion testing. A crucial factor influencing the
efficacy of the process is surface cleanliness, as contaminants between joining
partners can impede the effectiveness of the clinched joint. Therefore, all specimens
were meticulously cleaned prior to experimentation. This method exhibits promising
potential in creating clinched joints that align with the demands of flexible
manufacturing environments.

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: 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: 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: "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 conduction of structure-borne sound through joints causes energy dissipation.
The sound reduction index describes this energy loss as a level decrease in the
particle velocity across series-connected damping elements for which the superposition
principle applies. This simple model can help to develop a testing method for
joints based on this characteristic energy loss. In this paper, this model is
experimentally evaluated for multiple in-series clinched aluminium sheets. Samples
connected by several clinch points arranged in parallel are investigated experimentally,
and the results are discussed.
