text: "Abstract\r\n The effect of corrosion
on mechanically joined components is not well understood. While recent research
shows that a brief exposure of clinched specimens to a salt spray environment
improves the specimens’ fatigue life, other research shows a decrease in load
bearing capabilities with increasing corrosion times. These studies primarily
focus on galvanic corrosion. It is not entirely clear how other corrosion phenomena,
such as pitting corrosion, affect the fatigue life of clinched joints. In this
work, a numerical model is used, which is able to simulate corrosion pit growth
in EN AW-6014. The experimental polarization data of EN AW-6014 are used directly
in the calculation of the interface kinetics parameter of the model."

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: In this paper, a study based on experimental and numerical simulations is
performed to analyze fatigue cracks in clinched joints. An experimental investigation
is conducted to determine the failure modes of clinched joints under cyclic loading
at different load amplitudes with single-lap shear tests. In addition, numerical
FEM simulations of clinching process and subsequent shear loading are performed
to support the experimental investigations by analyzing the state of stresses
at the location of failure. An attempt is made to explain the location of crack
initiation in the experiments using evaluation variables such as contact shear
stress and maximum principal stress.

text: In addition to brazing and welding processes, mechanical joining processes
such as clinching are increasingly being used. Clinch joints offer an advantage
over metallurgical joining processes by giving the possibility of joining different
material combinations without typical drawbacks. Thereby clinching offers an enormous
advantage for lightweight construction. An additional benefit is a great variability
in the geometric shapes of the toolsets, which ensure optimum adaptation of the
clinching process on variations of the joining elements such as e.g. the sheet
thickness. However, the vast variability is also one of the major challenges regarding
the prediction of the joint reliability. In the work presented, the effect of
different toolset geometries was investigated with a particular focus on the interaction
between geometrical features and deformation-induced microstructural changes.
Light optical and electron microscopy techniques, as well as micro-hardness measurements,
were performed. The results were evaluated and discussed concerning the material's
deformation behavior, the change in geometrical shape and the microstructural
evolution due to the different tool geometries. The findings point out the main
influence factors regarding the mechanical properties in general and the fatigue
behavior in particular.

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: Clinching is the manufacturing process of joining two or more metal sheets
under high plastic deformation by form and force closure without thermal support
and auxiliary parts. Clinch connections are applicable to difficult-to-join hybrid
material combinations, such as steel and aluminum. Therefore, this technology
is interesting for the application of AISI 304 components, as this material is
widely used as a highly formable sheet material. A characteristic feature of AISI
304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can
transform into a significantly stronger body-centered cubic (bcc) α’-martensite
under plastic deformation. This work investigates the effect of heat treatment—a
process that involves the formation of an oxidation layer on the sheet surface—on
the forming process during joining and the resulting mechanical properties of
clinch joints made from AISI 304. For this purpose, different joints made from
non-heat treated and heat-treated sheets were examined using classical metallography
and advanced SEM techniques, accompanied by further investigations, such as hardness
and feritscope measurements. The shear tensile strength was determined, and the
fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced
surface roughness on the joint geometry and strength were observed.

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 this paper, a study based on experimental
and numerical simulations is performed to analyze fatigue cracks in clinched joints.
An experimental investigation is conducted to determine the failure modes of clinched
joints under cyclic loading at different load amplitudes with single-lap shear
tests. In addition, numerical FEM simulations of clinching process and subsequent
shear loading are performed to support the experimental investigations by analyzing
the state of stresses at the location of failure. An attempt is made to explain
the location of crack initiation in the experiments using evaluation variables
such as contact shear stress and maximum principal stress.

text: 'The use of clinch joints, e.g. vehicle structures, is determined by the reliability
of the joint and its strength properties - in particular the fatigue strength.
Clinch connections offer the advantage over form-closure and force-closure processes
that they can also be used for hybrid material combinations. In order to be able
to evaluate the influence of the geometry parameters such as e.g. undercut, neck
thickness or also base thickness on the fatigue behavior, three clinch connections
(in optimum and compromise design) with different tool parameters were designed
and examined using the example of a joining task with aluminum sheet material.
For this purpose, fatigue curves (F-N curves) in the range of high to very high
numbers of load cycles (N = 105 to 107) were determined. In this load cycle range,
a so-called "neck fracture" is mainly to be expected as the type of failure, whereas
for quasi-static tests, a “buckling” is more likely to occur. The tests were carried
out on single-cut overlapping shear tensile specimens. Metallographic and scanning
electron microscopic examinations of the joints and the fracture surfaces served
to identify the crack initiation site and to clarify the respective type of failure.
Significant differences in the damage behaviour of the three clinching variants
could be shown. This observation enables one step into the direction of fully
understanding the relationship along the causal chain "joint requirements - joining
process - fatigue strength". Thus the adaptability of the clinching process can
be improved. '
