text: "ABSTRACT\r\n Clinching
is a widely adopted joining technique in the automotive industry, enabling the
fabrication of lightweight structures from dissimilar sheet materials. Accurate
prediction of the fatigue life of clinched joints is essential for ensuring structural
safety and minimizing development costs. However, full 3D fatigue simulations
over millions of cycles are computationally intensive due to the complexity of
contact mechanics. This study introduces a 2D numerical model that circumvents
direct contact modeling by applying a slip condition at the sheet interface, significantly
reducing computational demands. A micro‐slip friction model is used to represent
the mechanical interface behavior, while a two‐scale damage model captures the
fatigue damage evolution. The model is validated against experimental data and
used to investigate the influence of friction coefficient and tangential contact
stiffness on fatigue life, highlighting its efficiency and predictive capability."

text: "Abstract\r\n Salt-spray
testing is widely used in the automotive and materials industries to assess the
corrosion resistance of protective coatings, where uniform corrosion is a key
indicator of material performance. This work presents a numerical uniform corrosion
model that predicts the corrosion rate of hot-dip zinc in salt-spray environments
by incorporating electrochemical reactions, mass transport via the Nernst–Planck
equation, and ionic-strength effects through the Brønsted–Bjerrum relation. The
model is calibrated using immersion-test data and extended to account for electrolyte
layer growth, droplet deposition, and periodic run-off in salt-spray environments.
The calibration establishes a relationship between the porosity of the zinc oxide
layer and the rate constant of zinc oxide precipitation. The validated model reproduces
the transition from activation- to diffusion-controlled corrosion and captures
the experimentally observed corrosion kinetics with an error margin of 20% when
electrolyte renewal is included. The results highlight the decisive role of electrolyte
dynamics in salt-spray environments and provide a foundation for extending the
framework to more complex cyclic corrosion tests."

text: "Abstract\r\n The effects of corrosion
on clinched joints are not completely understood yet. Recent research indicates
that galvanic corrosion can actually enhance the fatigue life of clinched joints.
It is then of significant interest to investigate the effects of another corrosion
phenomenon, pitting corrosion, on the fatigue behavior of clinched joints. Pitting
corrosion occurs in passive metals and can lead to stress concentrations. In the
present study, the effects of pitting corrosion are investigated by using Lemaitre’s
two-scale fatigue model with a 2D geometry of clinched joints. A slip condition
is applied as a boundary condition to simplify the clinched joint model and reduce
the computational cost of solving the contact mechanics problem. Additionally,
a method to determine the damage strength and the damage exponent used in the
two-scale damage model is introduced. Numerical simulations reveal that pitting
corrosion reduces the fatigue life of clinched joints, particularly when it occurs
on the internal surface in the neck area."

text: Abstract. The growing significance of lightweight design, reveals
drawbacks of conventional joining processes such as welding, which are known to
consume a considerable amount of energy. This fosters the use of mechanical joining
processes including clinching. However, the lack of universally applicable design
methods results in a cost- and time-intensive design process. The utilization
of machine learning methods can overcome these drawbacks. To ensure a reliable
clinch joint design, inherent uncertainties of the design parameter such as tool
deviations need to be considered in the design process. Varying distributions
of design parameters, due to changes in the manufacturing process, can lead to
high-computational effort in recalculating the resulting clinch joint properties
with numerical simulations. Current metamodel-based methods for consideration
of inherent uncertainties within the design parameters do not investigate the
transferability of metamodels to different distributions of design parameters,
which can lead to incorrect predictions. Therefore, this contribution investigates
the performance of several metamodels on differently distributed design parameters.
The obtained results indicate that metamodels demonstrate the best performance
when training and evaluation distributions are identical and that polynomial regression
models perform best on disparate distributions, when trained on uniform distributions.

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: Non-rotationally symmetrical joints can have different properties that can
be controlled by the joint orientation. This hypothesis is tested using a Reuleaux
triangle joint geometry. A tool design is carried out, followed by a numerical
sensitivity analysis of the tool geometry. Initial tools were manufactured for
experimental investigations and then adapted based on the findings of the sensitivity
analysis. The joints are characterized by micrographs, 3D scans, shear tensile
tests, head tensile tests and three-point bending tests and compared with a round
geometry. The analysis confirms the hypothesis. Thus, joints with adaptable properties
can be produced with one tool set.

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: Zur Prüfung der mechanischen Eigenschaften von mechanisch gefügten Verbindungen
wird gemäß der Normung in der Regel nur ein Fügepunkt verwendet. In diesem Beitrag
wird die Prüfung von Mehrfachanordnungen von Clinchpunkten in einem modifizierten
Torsionsversuch beschrieben. Bei den Fügeverbindungen der Proben aus artgleichen
Werkstoffen handelt es sich um zwei Varianten symmetrischer Mehrfachanordnungen
von vier Clinchpunkten mit zwei unterschiedlichen Fügepunktabständen, was zu zwei
verschiedenen Längen des Wirkabstands in Bezug auf die Rotationsachse im Torsionsversuch
führt. Das erste Teilziel der Untersuchung ist die Bewertung der Tragfähigkeit
der Mehrfachanordnungen von Clinchpunkten unter Torsionsbeanspruchung. Ein zweites
Teilziel ist die Analyse des Einflusses eines zusätzlichen Clinchpunkts, der als
Drehgelenk in der Rotationsachse wirkt, auf das Tragverhalten und das Versagensverhalten
der Fügeverbindung. Aus den erarbeiteten Resultaten werden Erkenntnisse zum Tragverhalten
der Fügeverbindungen abgeleitet und eine Überschlagsrechnung vorgestellt, um Richtlinien
zur konstruktiven Auslegung von Bauteilen aufzustellen.

text: Durch eine zunehmende Verbreitung von Clinchverbindungen in industriellen
Anwendungen spielt die Zuverlässigkeit der Fügeverbindung eine immer größere Rolle.
Insbesondere Mehrfachanordnungen von Clinchpunkten wurden bisher nur selten untersucht.
In der vorliegenden Arbeit wird die Zuverlässigkeit von gefügten Proben mit einer
Mehrfachanordnung von Clinchpunkten unter zyklischer Beanspruchung untersucht.
Ziel ist es, die Wechselwirkung benachbarter Clinchpunkte und deren Einfluss auf
die Ermüdungslebensdauer zu untersuchen. Dazu wurden Proben mit variierenden Fügepunktabständen
hergestellt und in Versuchsreihen zyklisch belastet. Die Resultate zeigen, dass
die räumliche Anordnung der Clinchpunkte das Ermüdungsverhalten beeinflusst. Es
wurde festgestellt, dass bei Mehrfachanordnungen sowohl der Fügepunktabstand als
auch der Abstand der Fügepunkte zum Bauteilrand in Belastungsrichtung einen Einflussfaktor
darstellen. Die vorliegende Arbeit leistet somit einen Beitrag zur Lebensdauervorhersage
gefügter Strukturen und bildet eine Grundlage für weiterführende Untersuchungen
zu Gestaltungsempfehlungen.

text: The accurate prediction of crack initiation and propagation is essential
for assessing the structural integrity of mechanically joined components and other
complex assemblies. To overcome the limitations of existing finite element tools,
a modular Python framework has been developed to automate three-dimensional crack
growth simulations. The program combines geometric reconstruction, adaptive remeshing,
and the numerical evaluation of fracture mechanics parameters within a single,
fully automated workflow. The framework builds on open-source components and remains
solver-independent, enabling straightforward integration with commercial or research
finite element codes. A dedicated sequence of modules performs all required steps,
from mesh separation and crack insertion to local submodeling, stress and displacement
mapping, and iterative crack-front update, without manual interaction. The methodology
was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case.
The numerical results demonstrate the accurate reproduction of stress intensity
factors and energy release rates while achieving high computational efficiency
through localized refinement. The developed approach provides a robust basis for
crack growth simulations of geometrically complex or residual stress-affected
structures. Its high degree of automation and flexibility makes it particularly
suited for analyzing cracks in clinched and riveted joints, supporting the predictive
design and durability assessment of joined lightweight structures.

text: Focusing on upcoming challenges in lightweight design, such as increasing
emission targets or novel multimaterial connections, versatile applicable and
environmentally friendly production technologies are crucial. In this context,
mechanical joining technology clinching offers a fast and energy-efficient procedure
for assembling sheet metals, being a proper alternative to established joining
methods, such as spot welding. However, the design of clinch points is a challenge,
which is partly supported by numerical or data-based approaches for optimal tool
dimensions assuring proper joint characteristics. While this is usually done for
an ideal environment, real joining processes are characterized by multiple inevitably
varying parameters, e.g. of the material, which have a significant impact on the
quality of clinch points. Therefore, this contribution addresses the current gap
by analyzing the effect of parameter variations or uncertainties on the resulting
joint characteristics and studying the impact of the nominal tool design. Thus,
an efficient meta-model-based variation simulation procedure is proposed and used
for analyzing the effect of different tool design configurations and variation
scenarios. Based on the results, it was found that varying process parameters
have a strong impact on the resulting joint characteristics, whereby the effect
significantly depends on the nominal tool design. This reveals the potential for
a robust tool design and implies that the nominal tool design and the tolerancing
of parameters should be done simultaneously for a reliable virtual joining point
design without extensive iterations and physical tests.

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: 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.
