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: '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: "Lightweight construction has increasingly become the focus of scientific
research in recent years, not least due to\r\nthe constantly increasing fuel price,
which is a key factor in the economic viability of many companies. In this\r\nrespect,
the use of hybrid structures, made of dissimilar materials offers many advantages.
However, such hybrid\r\nstructures often have undesirable side effects. For example,
brittle intermetallic phases are formed when\r\naluminum and steel are welded.
Clinching as a mechanical joining process does not produce such intermetallic\r\nphases
since the connection is realized through form and force closure. In this process,
a punch passes through\r\ntwo or more sheets and forms them into a permanent joint
in a die. In the present work, the corrosion phenomena\r\nof an aluminum-steel
clinched joint have been investigated by both experiments and numerical simulations
in\r\norder to explain the superior fatigue behavior of pre-corroded joints. Therefore,
the clinched joints have been\r\ncorroded by a three-week salt-spray test. In
addition, the electric potential and the von Mises stress are calculated\r\nunder
the assumption of a static loading. The results of both experiments and numerical
simulations can explain\r\nthe improvement in the fatigue behavior of the corroded
specimens. This phenomenon can be attributed to the\r\naccumulation of corrosion
products in small gaps between the joined metal sheets."

text: Predicting the durability of components subjected to mechanical load under
environmental conditions leading to corrosion is one of the most challenging tasks
in mechanical engineering. The demand for precise predictions increases with the
desire of lightweight design in transportation due to environmental protection.
Corrosion with its manifold of mechanisms often occurs together with the production
of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the
most feared damage mechanisms for metal constructions often leading to early and
unexpected failure. Until now, predictions are mostly based on costly experiments.
Hence, a rational predictive model based on the fundamentals of electrochemistry
and damage mechanics has to be developed in order to reduce the costs. In this
work, a first model approach based on classical continuum damage mechanics is
presented to couple both, the damage induced by the mechanical stress and the
hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent
theory is applied to describe the mechanical damage due to fatigue. The electrochemical
kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion
equation to consider the impact of hydrogen embrittlement on the fatigue. The
modeling of the mechanism of hydrogen embrittlement defines the progress of damage
accumulation due to the electrochemistry. The durability results like the S-N
diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue
frequency or the stress ratio.

text: Galvanic corrosion is a destructive process between dissimilar metals. The
present paper presents a constructed numerical test case to simulate galvanic
corrosion of two dissimilar metals. This test case is used to study the accuracy
of different implementations to track the dissolving anode boundary. One technique
is to numerically simulate a mesh displacement based on the prescribed displacement
at the anode boundary. The second method is to adjust only the boundary elements.
Re-meshing after a certain number of time steps is applied to both implementations.
They produce similar results for an electrical and electrochemical field problem.
This work shows that mesh smoothing does not result in higher accuracy when modeling
a moving anode front. Adjusting only the boundary elements is sufficient when
frequent re-meshing is used.

text: Mechanical clinching is used to create lightweight hybrid structures. In order
to estimate the service life of clinched components, its fatigue properties need
to be known under different mechanical loading conditions. In addition to fatigue,
corrosion is another factor that affects the fatigue life of clinched joints.
In the literature, many corrosion and high-cycle fatigue damage models exist.
However, little is known about how both phenomena interact in clinched joints.
In this article, the influence of galvanic corrosion on clinched EN AW-6014/HCT590X + Z
sheets on the fatigue life is investigated by means of numerical simulations and
experimental results. An accurate prediction of the Wöhler lines of non-corroded
and pre-corroded clinched specimens is shown.

text: 'Corrosion is a major cause for the failure of metallic components in various
branches of the industry. Depending on the corrosion severity, the time until
failure of the component varies. On the contrary, a study has shown that certain
riveted metal joints, exposed to a short period of mechanical loading and corrosion,
have greater fatigue limits. This study gives rise to the question how different
corrosion exposure times affect joint metallic components. In the present research,
a theoretical approach is developed in order to evaluate the influence of galvanic
corrosion on joint integrity of clinched metal joints. At first, the framework
for modeling galvanic corrosion is introduced. Furthermore, a simulative investigation
of a clinching point is carried out based on the assumption that corrosion leads
to a reduction of the contact area which leads to a local increase in contact
pressure. For this purpose, the stiffness values of individual elements in a finite
element model are reduced locally in the contact area of the undercut and the
contact stress along a path is evaluated. Summarizing, a modeling approach is
introduced to investigate corrosion effects on load-bearing behavior of clinched
joints. '

text: Predicting the durability of components under mechanical loading combined
with environmental conditions leading to corrosion is one of the most challenging
tasks in mechanical engineering. Precise predictions are neccesary for lightweight
design in transportation due to environmental protection. During corrosion often
hydrogen is produced by electrochemical reactions. Hydrogen embrittlement is one
of the most feared damage mechanisms for metal constructions leading to early
and unexpected failure. Until now predictions are mostly done through costly experiments.
In the present research, a first simple simulation model based on the fundamentals
of electrochemistry and continuum damage mechanics is developed to couple the
damage induced by the mechanical stress with the hydrogen embrittlement. Results
of the durability are presented for the case of uniaxial cyclic loading for varying
testing frequency.
