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: The trend towards lightweight design, driven by increasingly stringent emission
targets, poses challenges to conventional joining processes due to the different
mechanical properties of the joining partners used to manufacture multi-material
systems. For this reason, new versatile joining processes are in demand for joining
dissimilar materials. In this regard, pin joining with cold extruded pin structures
is a relatively new, two-stage joining process for joining materials such as high-strength
steel and aluminium as well as steel and fibre-reinforced plastic to multi-material
systems, without the need for auxiliary elements. Due to the novelty of the process,
there are currently only a few studies on the robustness of this joining process
available. Thus, limited statements on the stability of the joining process considering
uncertain process conditions, such as varying material properties or friction
values, can be provided. Motivated by this, the presented work investigates the
influence of different uncertain process parameters on the pin extrusion as well
as on the joining process itself, carrying out a systematic robustness analysis.
Therefore, the methodical approach covers the complete process chain of pin joining,
including the load-bearing capacity of the joint by means of numerical simulation
and data-driven methods. Thereby, a deeper understanding of the pin joining process
is generated and the versatility of the novel joining process is increased. Additionally,
the provision of manufacturing recommendations for the forming of pin joints leads
to a significant decrease in the failure probability caused by ploughing or buckling
effects.

text: Deformation of continuous fibre reinforced plastics during thermally-assisted
forming or joining processes leads to a change of the initial material structure.
The load behaviour of composite parts strongly depends on the resultant material
structure. The prediction of this material structure is a challenging task and
requires a deep knowledge of the material behaviour above melting temperature
and the occurring complex forming phenomena. Through this knowledge, the optimisation
of manufacturing parameters for a more efficient and reproducible process can
be enabled and are in the focus of many investigations. In the present paper,
a simplified pultrusion test rig is developed and presented to investigate the
deformation behaviour of a thermoplastic semi-finished fiber product in a forming
element. Therefore, different process parameters, like forming element temperature,
pulling velocity as well as the forming element geometry, are varied. The deformation
behaviour in the forming zone of the thermoplastic preimpregnated continuous glass
fibre-reinforced material is investigated by computed tomography and the resultant
pulling forces are measured. The results clearly show the correlation between
the forming element temperature and the resulting forces due to a change in the
viscosity of the thermoplastic matrix and the resulting fiber matrix interaction.
In addition, the evaluation of the measurement data shows which forming forces
are required to change the shape of the thermoplastic unidirectional material
with a rectangular cross-section to a round one.

text: Pin extrusion is a common process to realise pin structures in different geometrical
dimensions for a subsequent joining operation. Nevertheless, the process of pin
extrusion offers process limits regarding sheet thinning as a consequence of the
punch penetration depth into the sheet. Thereby, cracks at the residual sheet
thickness can occur during strength tests, resulting in a failure of the complete
joint due to severe thinning. Therefore, measures have to be taken into account
to reduce the thinning. One possibility is the application of orbital formed tailored
blanks with a local material pre-distribution, which allows a higher sheet thickness
in the desired area. Within this contribution, the novel approach of a process
combination of orbital forming and pin extrusion is investigated. To reveal the
potential of a local material pre-distribution, conventional specimens are compared
with previously orbital formed components. Relevant parameters such as the residual
sheet thickness, the pin height as well as the average hardness values are compared.
The results show a significant positive influence of a local material pre-distribution
on the residual sheet thickness as well as the resulting pin height. Furthermore,
the strain hardening during orbital forming can be seen as an additional advantage.
To conclude the results, the process limits of conventional pin extrusion can
be expanded significantly by the application of specimens with a local material
pre-distribution.

text: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'

text: This article presents the application and evaluation of a cantilever with
integrated sensing and actuation as part of an atomic force microscope (AFM) with
an adjustable probe direction, which is integrated into a nano measuring machine
(NMM-1). The AFM, which is operated in closed-loop intermittent contact mode,
is based on two rotational axes that enable the adjustment of the probe direction
to cover a complete hemisphere. The axes greatly enlarge the metrology frame of
the measuring system by materials with a comparatively high coefficient of thermal
expansion, which ultimately limits the achievable measurement uncertainty of the
measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign
of the rotational kinematics is mandatory. However, in this article, some preliminary
investigations on the application of a self-sensing cantilever with an integrated
micro heater for its stimulation will be presented. In previous investigations,
a piezoelectric actuator has been applied to stimulate the cantilever. However,
the removal of the piezoelectric actuator, which is enabled by the application
of a cantilever with an integrated micro heater, promises an essential simplification
of the sensor holder. Thus, in the future it might be possible to use materials
with a low coefficient of thermal expansion, which are often difficult to machine
and therefore only allow for rather simple geometries. Furthermore, because of
the creepage of piezoelectric actuators, their removal from the metrology frame
might lead to improved metrological characteristics. As will be shown, there are
no significant differences between the two modes of actuation. Therefore, the
redesigned rotational system will be based on the cantilever with integrated sensing
and actuation.

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: Joining by forming operations presents powerful and complex joining techniques.
Clinching is a well-known joining process for use in sheet metalworking. Currently,
clinched joints are focusing on mechanically enhanced connections. Additionally,
the demand for integrating electrical requirements to transmit electrical currents
will be increased in the future. This integration is particularly important, for
instance, in the e-mobility sector. It enables connecting battery cells with electrical
joints of aluminum and copper. Systematic use of the process-specific advantages
of this joining method opens up the possibility to find and create electrically
optimized connections. The optimization for the transmission of electrical currents
will be demonstrated for clinched joints by adapting the tool geometry and the
clinched joint design. Based on a comparison of the electrical joint resistance,
the limit use temperature is defined for the joining materials used based on the
microstructural condition and the aging condition due to artificial aging. As
a result of the investigations carried out, reliable current transmission at a
constant conductor temperature of up to 120 °C can be achieved for clinched copper–copper
joints. In the case of pure aluminum joints and mixed joints of aluminum and copper,
long-term stable current transmission can be ensured up to a conductor temperature
of 100 °C.

text: A virtual test setup for investigating single fibres in a transverse shear
flow based on a parallel-plate rheometer is presented. The investigations are
carried out to verify a numerical representation of the fluid–structure interaction
(FSI), where Arbitrary Lagrangian–Eulerian (ALE) and computational fluid dynamics
(CFD) methods are used and evaluated. Both are suitable to simulate flexible solid
structures in a transverse shear flow. Comparative investigations with different
model setups and increasing complexity are presented. It is shown, that the CFD
method with an interface-based coupling approach is not capable of handling small
fibre diameters in comparison to large fluid domains due to mesh dependencies
at the interface definitions. The ALE method is more suited for this task since
fibres are embedded without any mesh restrictions. Element types beam, solid,
and discrete are considered for fibre modelling. It is shown that the beam formulation
for ALE and 3D solid elements for the CFD method are the preferred options.

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: As a joining-by-forming process, clinching and the use of functional elements
enable low-energy joining of components through form, force, and, under certain
conditions, material closure. In addition to the transmission of mechanical forces,
these joining processes can be qualified for additional electrical contact within
the scope of functional integration for electro-mobile applications. For this
purpose, maximizing the force and material closure is necessary to ensure a long-term,
stable transmission of electrical currents. To this end, the electrical properties
of the joints were optimized. The investigations carried out show the long-term
behavior under normal operating conditions and the short-circuit case.

text: Clinching is a cost efficient method for joining components in series production.
To assure the clinch point’s quality, the force displacement curve during clinching
or the bottom thickness are monitored. The most significant geometrical characteristics
of the clinch point, neck thickness and undercut, are usually tested destructively
by microsectioning. However, micrograph preparation goes ahead with a resetting
of elastic deformations and crack-closing after unloading. To generate a comprehensive
knowledge of the clinch point’s inner geometry under load, in-situ computed tomography
(CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive
to the inner state of the clinch point, it could detect critical events like crack
development during loading. If such events are indicated, the loading process
is stopped and a stepped in-situ CT of the following crack and deformation development
is performed. In this paper, the concept is applied to the process of clinching
itself, providing a detailed three-dimensional insight in the development of the
joining zone. A test set-up is used which allows a stepwise clinching of two aluminium
sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system.
In order to minimize X-ray absorption, a beryllium cylinder is used within the
set-up frame and clinching tools are made from Si3N4. The actuator and sensor
necessary for the TDA are integrated in the set-up. In regular process steps,
the clinching process is interrupted in order to perform a TDA and a CT scan.
In order to enhance the visibility of the interface, a thin tin layer is positioned
between the sheets prior clinching. It is shown, that the test-set up allows a
monitoring of the dynamic behaviour of the specimen during clinching while the
CT scans visualize the inner geometry and material flow non-destructively.
