text: The focus towards multi-material and lightweight assemblies, driven by legal
requirements on reducing emissions and energy consumptions, reveals important
drawbacks and disadvantages of established joining processes, such as welding.
In this context, mechanical joining technologies, such as clinching, are becoming
more and more relevant especially in the automotive industry. However, the availability
of only few standards and almost none systematic design methods causes a still
very time- and cost-intensive assembly development process considering mainly
expert knowledge and a considerable amount of experimental studies. Motivated
by this, the presented work introduces a novel approach for the methodical design
and dimensioning of mechanically clinched assemblies. Therefore, the utilization
of regression models, such as machine learning algorithms, combined with manufacturing
knowledge ensures a reliable estimation of individual clinched joint characteristics.
In addition, the implementation of an engineering workbench enables the following
data-driven and knowledge-based generation of high-quality initial assembly designs
already in early product development phases. In a subsequent analysis and adjustment,
these designs are being improved while guaranteeing joining safety and loading
conformity. The presented results indicate that the methodological approach can
pave the way to a more systematic design process of mechanical joining assemblies,
which can significantly shorten the required number of iteration loops and therefore
the product development time.

text: The combination of the mechanical properties of a clinched joint and of the
material surrounding the joint determine the resulting properties of the component
and joint. The cause and effect relationships between the joint and the joint
environment offers the possibility of a specific modification through an adaptation
in the design process. In order to identify these cause and effect relationships
and resulting interactions experimentally, numerous of experiments are required.
In this publication, a concept for the automated manufacturing of head tensile
test and shear tensile test specimens – from cutting to clinching – by using a
punch laser machine is presented. Based on a full-factorial experimental design,
the parameters change of the properties of the joint environment by beading and
change of the punch displacement are addressed. The influence on the properties
of the clinched specimen is evaluated based on the variables Stiffness, force
at the beginning of yielding and maximum force at head tensile loading and shear
tensile loading. In addition, the geometric quality parameters of neck thickness,
interlock and bottom thickness are evaluated. The relationships can be used to
apply uniform loads to joints in joined structures to counteract oversizing.

text: The demands on joining technology are constantly increasing due to
the consistent lightweight construction and the associated increasing material
mix. To meet these requirements, the adaptability of the joining processes must
be improved to be able to process different material combinations and to react
to challenges caused by deviations in the process chain. One example of a highly
adaptable process due to the two-step process sequence is thermomechanical joining
with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to
the joint. In this paper, the potentials of the adaption in the two-stage joining
process with aluminium auxiliary joining elements are investigated. To this end,
it is first investigated whether a thermomechanical forming process can be used
to achieve a uniform and controlled manufacturing regarding the process variable
of the temperature as well as the geometry of the FSJC. Based on the successful
proof of the high and good repeatability in the FSJC manufacturing, possibilities,
and potentials for the targeted influencing of the process and FSJC geometry are
shown, based on an extensive variation of the process input variables (delivery
condition and thus mechanical properties of the raw parts as well as the process
parameters of rotational speed and feed rate). Here it can be shown that above
all, the feed rate of the final forming process has the strongest influence on
the process and thus also offers the strongest possibilities for influencing it.

text: Due to current global challenges regarding energy security as well as climate
change the importance of preserving the nature and all available resources is
steadily increasing. In order to achieve the energy-saving and climate targets,
it is not only necessary to develop new processes and processing possibilities,
but also to optimise known process chains with regard to energy and resource efficiency
in the area of production technology. Here, the recycling of supposed production
waste represents an opportunity to save energy. In addition to the conventional
and smelting metallurgical recycling process, extensive research activities have
therefore been carried out for alternative solid-state recycling processes. One
example is the friction-induced recycling process, which has been used in past
studies to demonstrate the energy- and resource-efficient production of semi-finished
products from aluminium scrap such as chips. In addition, properties like chemical
composition and strength can be adjusted locally and in terms of processing time.
This can be used to improve the versatility of further processing steps.

text: Consistent lightweight construction in the area of vehicle manufacturing requires
the increased use of multi-material combinations. This, in turn, requires an adaptation
of standard joining techniques. In multi-material combinations, the importance
of integral cast components, in particular, is increasing and poses additional
technical challenges for the industry. One approach to solve these challenges
is adaptable joining elements manufactured by a thermomechanical forming process.
By applying an incremental and thermomechanical joining process, it is possible
to react immediately and adapt the joining process inline to reduce the number
of different joining elements. In the investigation described in this publication,
cast plates made of the cast aluminium alloy EN AC-AlSi9 serve as joining partners,
which are processed by sand casting. The joining process of hypoeutectic AlSi
alloys is challenging as their brittle character leads to cracks in the joint
during conventional mechanical joining. To solve this, the frictional heat of
the novel joining process applied can provide a finer microstructure in the hypoeutectic
AlSi9 cast alloy. In detail, its Si is finer-grained, resulting in higher ductility
of the joint. This study reveals the thermomechanical joining suitability of a
hypoeutectic cast aluminium alloy in combination with adaptively manufactured
auxiliary joining elements.

text: Das umformtechnische Fügeverfahren Clinchen ermöglicht ein energiearmes Fügen
von Blechen und dient traditionell der Übertragung mechanischer Kräfte. Neue Einsatzgebiete
erfordern eine elektrische oder thermische Leitfähigkeit, sodass es notwendig
ist, das Clinchen entsprechend zu qualifizieren. Es wurden Untersuchungen an Aluminiumverbindungen
durchgeführt, welche mit hohen Kurzzeitströmen belastet wurden. Der Einfluss verschiedener
Oberflächenvorbehandlungen wurde betrachtet. Als Charakterisierungsmethode für
die Bauteile und die geclinchten Fügeverbindungen wird die Messung des elektrischen
Widerstandes herangezogen. Die untersuchten Clinchverbindungen sind fähig, die
im Fehlerfall auftretenden Kurzzeitströme zu übertragen. Der Oberflächenzustand
übt dabei einen signifikanten Einfluss auf die Clinchpunktausbildung und damit
auf deren elektrische Eigenschaften aus. Durch Messung des elektrischen Widerstandes
vor und nach dem Fügen sowie nach einer Bestromung mit Fehlerströmen, kann das
Kontaktverhalten qualifiziert werden.

text: 'The application of the mechanical joining process clinching allows the assembly
of different sheet metal materials with a wide range of material thickness configurations,
which is of interest for lightweight multi-material structures. In order to be
able to predict the clinched joint properties as a function of the individual
manufacturing steps, current studies focus on numerical modeling of the entire
clinching process chain. It is essential to be able to take into account the influence
of the joining process-induced damage on the load-bearing capacity of the joint
during the loading phase. This study presents a numerical damage accumulation
in the clinching process based on an implemented Hosford-Coulomb failure model
using a 3D clinching process model applied on the aluminum alloy EN AW-6014 in
temper T4. A correspondence of the experimentally determined failure location
with the element of the highest numerically determined damage accumulation is
shown. Moreover, the experimentally determined failure behavior is predicted to
be in agreement in the numerical loading simulation with transferred pre-damage
from the process simulation. '

text: Requirements of multi-material construction involve adjustments to standard
joining techniques. Especially the growing importance of integral cast components
poses additional engineering challenges for the industry. One approach to achieve
these goals are adaptable joining elements formed by friction spinning. This approach
uses friction-induced heat to form customisable joining elements to join sheets
for different boundary conditions, even for brittle cast materials. It is possible
to react immediately to adapt to the joining process inline and reduce the amount
of different joining elements. As the joining partner serve casting plates of
the aluminium casting alloy EN AC–AlSi9, which is processed in the sand casting.
Joining hypoeutectic AlSi alloys constitutes a challenge because the brittle character
of these cause cracks in the joint during conventional mechanical joining. Furthermore,
the friction-induced heat of the novel joining process causes a finer microstructure
in the hypoeutectic AlSi9 casting alloy. In particular, the eutectic Si is more
fine-grained, resulting in higher joint ductility. This study indicates the joining
suitability of a hypoeutectic aluminium casting alloy in combination with adaptive
manufactured additional joining elements. Here, various mechanical and microstructural
investigations validate the influence of the thermomechanical joining technique.
In conclusion, the potential of this joining process is presented regarding the
joinability of cast aluminium components.

text: Multi-material designs (MMD) are more frequently used in the automotive industry.
Hereby, the combination of different materials, metal sheets, or cast components,
is mechanically joined, often by forming joining processes. The cast components
mostly used are high-strength, age-hardenable aluminium alloys of the Al–Si system.
Here, the low ductility of the AlSi alloys constitutes a challenge because their
brittle nature causes cracks during the joining process. However, by using suitable
solidification conditions, it is possible to achieve a microstructure with improved
mechanical and joining properties. For this study, we used the twin-roll casting
process (TRC) with water-cooled rollers to manufacture the hypoeutectic AlSi10Mg
for the first time. Hereby, high solidification rates are realisable, which introduces
a microstructure that is about four times finer than in the sand casting process.
In particular, it is shown that a fine microstructure close to the modification
with Na or Sr is achieved by the high solidification rate in the TRC process without
using these elements. Based on this, the mechanical properties increase, and especially
the ductility is enhanced. Subsequent joining investigations validate the positive
influence of a high solidification rate since cracks in joints can be avoided.
Finally, a microstructure-property-joint suitability correlation is presented.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

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: 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: "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: Resource-saving and sustainable production is becoming increasingly important
regarding social, political and economic aspects, thus making the use of lightweight-construction
technologies a current trend. For this reason, multi-material-systems made of
high-strength steel and aluminium as well as metal and fibre-reinforced plastics
gain in importance. However, different material properties, e.g. stiffness, thermal
expansion coefficients or chemical incompatibilities, are challenging for conventional
joining technologies. Joining by cold formed pin structures has shown to have
high potential for joining multi-material-systems. These pins can be joined either
by direct pin pressing into an unperforated joining partner or by caulking, where
the pins are inserted through a pre-punched joining partner and the pin head is
upset, resulting in a form-fit joint. Usually, cylindrical pins are used for joining.
However, non-rotationally symmetrical pin geometries offer the possibility of
introducing a predetermined breaking point or reinforcing a connection in the
principal force direction. In this work, cylindrical pins as well as non-rotationally
symmetrical pin geometries, such as polygonal and oval pin structures, are cold
extruded from the sheet metal plane of an HCT590X+Z dual phase steel and joined
in the next step with an EN AW-6014 aluminium using direct pin pressing. Since
the formation of an undercut has an crucial influence on the joint strength, the
investigations will be focused on the resulting joint geometry. In addition, the
effect of different pin heights will be examined to analyse the joint formation
at different levels of compression of the pin structures. Finally, the joints
are evaluated regarding their joint strength in tensile shear tests and cross
tension tests. Here the flow resistance of the geometry used as well as the pin
height and thus the strain hardening of the pin base during the extrusion of the
pins play a decisive role for the shear strength.

text: In this study, quasi-unidirectional continuous fiber reinforced thermoplastics
(CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and
polygonal pin structures which are directly pressed into the CFRT component after
local infrared heating. In comparison to already available studies, the unique
novelty is the use of non-rotational symmetric pin structures for the CFRT/metal
hybrid joining. Thus, a variation in the fiber orientation in the CFRT component
as well as a variation in the non-rotational symmetric pins’ orientation in relation
to the sample orientation is conducted. The created samples are consequently mechanically
tested via single lap shear experiments in a quasi-static state. Finally, the
failure behavior of the single lap shear samples is investigated with the help
of microscopic images and detailed photographs. In the single lap shear tests,
it could be shown that non-rotational symmetric pin structures lead to an increase
in maximum testing forces of up to 74% when compared to cylindrical pins. However,
when normalized to the pin foot print related joint strength, only one polygonal
pin variation showed increased joint strength in comparison to cylindrical pin
structures. The investigation of the failure behavior showed two distinct failure
modes. The first failure mode was failure of the CFRT component due to an exceedance
of the maximum bearing strength of the pin-hole leading to significant damage
in the CFRT component. The second failure mode was pin-deflection due to the applied
testing load and a subsequent pin extraction from the CFRT component resulting
in significantly less visible damage in the CFRT component. Generally, CFRT failure
is more likely with a fiber orientation of 0° in relation to the load direction
while pin extraction typically occurs with a fiber orientation of 90°. It is assumed
that for future investigations, pin structures with an undercutting shape that
creates an interlocking joint could counteract the tendency for pin-extraction
and consequently lead to increased maximum joint strengths.

text: 'Thermoplastic composites (TPCs) are predestined for use in lightweight structures,
especially for high-volume applications. In many cases, joining is a key factor
for the successful application of TPCs in multi-material systems. Many joining
processes for this material group are based on warm forming the joining zone.
This results in a change of the local material structure characterised by modified
fibre paths, as well as varying fibre contents, which significantly influences
the load-bearing behaviour. During the forming process, many different phenomena
occur simultaneously at different scales. In this paper, the deformation modes
and flow mechanisms of TPCs during forming described in the literature are first
analysed. Based on this, three different joining processes are investigated: embedding
of inserts, moulding of contour joints, and hotclinching. In order to identify
the phenomena occurring in each process and to describe the characteristic resulting
material structure in the joining zones, micrographs as well as computed tomography
(CT) analyses are performed for both individual process stages and final joining
zones.'

text: Unter dem Begriff der Auflösung wird für gewöhnlich das kleinste messbare
Merkmal eines Messsystems verstanden. In der dimensionellen Computertomografie
hingegen haben sich in den vergangenen Jahren mehrere Auflösungskonzepte etabliert,
die aufgrund der fehlenden Normung zueinander im Kontrast stehen. In diesem Beitrag
werden die drei häufigsten Konzepte, die Voxelgröße, die Ortsauflösung und die
metrologische Strukturauflösung in Kürze vorgestellt. Anschließend wird eine Abgrenzung
zwischen den Konzepten getroffen und ein Integration der bestehenden Konzepte
in ein gemeinsames Amplituden-Wellenlängen Diagramm diskutiert.
