text: 'Abstract. Accurate Finite Element Modeling (FEM) of joints is essential
in the design of complex mechanical systems such as automotive body-in-white (BIW)
structures, as it plays a critical role in evaluating their performance. Although
well-established techniques exist for modeling rotationally symmetric joints,
there remains a significant gap in effectively modeling non-rotationally symmetric
joints. These joints are particularly relevant in the automotive BIW, where they
can better accommodate anisotropic loading conditions. In this study, strategies
for modeling non-rotationally symmetric joints were explored using finite element
simulations in LS-DYNA. The findings demonstrate that discrete beam elements can
capture the anisotropic characteristics of such joints. Two models were tested:
a single-beam model for stiffness periodicity every 90°, and a three-beam model
for stiffness periodicity every 120°. Force responses, stress distribution, and
sheet bending behaviors were analyzed, confirming that discrete beam elements
can accurately represent direction-dependent stiffness. These results establish
a foundation for developing advanced joint modeling strategies in complex mechanical
systems.'

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: This paper focuses on the failure behavior of specimens with various configurations
of clinched joints under shear tensile loading. The primary objective is to assess
the influence of the joining direction and the spatial arrangement of clinched
joints on their mechanical performance. A number of experiments was conducted,
focusing on three clinched joints arranged in different configurations, each varying
in terms of joining direction and spacing. These configurations were subjected
to shear tensile tests, with force-displacement curves recorded for each sample
to provide a detailed characterization of their structural response. The experimental
findings indicate that the specific arrangement of the clinched joints, in terms
of joining direction, has a marginal impact on the overall failure behavior. This
suggests that intricate modifications to the joining direction are unnecessary
to achieve improved mechanical performance in such applications. These results
offer valuable insights for the design of clinched joint assemblies, indicating
that simplified joining strategies may suffice without compromising structural
integrity under shear loading.

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: This paper discusses the influence of joint orientation with non-rotationally
symmetric geometry, on load distribution and structural behavior. The focus is
on understanding how changes in the alignment of individual joints affect the
distribution of load, neighboring joints, and the overall performance of the component.
Lap shear specimens with multiple joints arranged in a line are analyzed to explore
these effects. Simplified models are used to model the joints in finite element
simulations, allowing for efficient yet accurate analysis of the load distribution
and structural response under varying joint orientations. Variations in joint
orientation result in measurable changes in the distribution of forces on adjacent
joints, influencing their behavior and that of the overall assembly. Experimental
validation confirms the numerical results, providing deeper insights into the
interaction between individual joints and their surroundings. This work contributes
to the development of systematic approaches for optimizing the design of components
with non-rotationally symmetric joints. The study highlights the importance of
considering directional properties of joints in designing structural components.

text: Abstract. Traditionally, joints are cylindrical and rotationally symmetric.
In the present study, non-rotationally symmetric joints are used for joining steel
and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also
analyzes the impact of non-rotational symmetric joint rotation on the load-bearing
capacity. Single lap joint specimens were fabricated using the In-Mold assembly
technique for joining steel sheets with GMT. Tensile shear tests were performed
on different orientations of the joint geometry, and it was observed that changing
the joint orientation influences the load-bearing capacity. The joints are constitutively
modeled using beam elements and the influence of joint rotation on load distribution
is examined through a static simulation study.

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.

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: Clinching is a joining process that is becoming more and more important in
industry due to the increasing use of multi-material designs. Despite the already
widespread use of the process, there is still a need for research to understand
the mechanisms and design of clinched joints. In contrast to the tool parameters,
process and material disturbances have not yet been investigated to a relatively
large extent. However, these also have a great influence on the properties and
applicability of clinching. The effect of process disturbances on the clinched
joint are investigated with numerical and experimental methods. The investigated
process variations are the history of the sheets using the pre-hardening of the
material, different sheet thicknesses, sheet arrangements and punch strokes. For
the consideration of the material history, a specimen geometry for pre-stretching
specimens in uniaxial tension is used, from which the pre-stretched secondary
specimens are taken. A finite element model is set up for the numerical investigations.
Suitable clinching tools are selected. With the simulation, selected process influences
can be examined. The effort of the numerical investigations is considerably reduced
with the help of a statistical experimental design according to Taguchi. To confirm
the simulation results, experimental investigations of the clinch point geometry
by using micrographs and the shear strength of the clinched joint are performed.
The analysis of the influence of difference disturbance factors on the clinching
process demonstrate the importance of the holistic view of the clinching process.

text: Mechanical joining technologies are increasingly used in multi-material lightweight
constructions and offer opportunities to create versatile joining processes due
to their low heat input, robustness to metallurgical incompatibilities and various
process variants. They can be categorised into technologies which require an auxiliary
joining element, or do not require an auxiliary joining element. A typical example
for a mechanical joining process with auxiliary joining element is self-piercing
riveting. A wide range of processes exist which are not requiring an auxiliary
joining element. This allows both point-shaped (e.g., by clinching) and line-shaped
(e.g., friction stir welding) joints to be produced. In order to achieve versatile
processes, challenges exist in particular in the creation of intervention possibilities
in the process and the understanding and handling of materials that are difficult
to join, such as fiber reinforced plastics (FRP) or high-strength metals. In addition,
predictive capability is required, which in particular requires accurate process
simulation. Finally, the processes must be measured non-destructively in order
to generate control variables in the process or to investigate the cause-effect
relationship. This paper covers the state of the art in scientific research concerning
mechanical joining and discusses future challenges on the way to versatile mechanical
joining processes.

text: The components of a body in white consist of many individual thin-walled sheet
metal parts, which usually are manufactured in deep-drawing processes. In general,
the conditions in a deep-drawing process change due to changing tribology conditions,
varying degrees of spring back, or scattering material properties in the sheet
blanks, which affects the resulting pre-strain. Mechanical joining processes,
especially clinching, are influenced by these process-related pre-strains. The
final geometric shape of a clinched joint is affected to a significant level by
the prior material deformation when joining with constant process parameters.
That leads to a change in the stiffness and force transmission in the clinched
joint due to the different geometric dimensions, such as interlock, neck thickness
and bottom thickness, which directly affect the load bearing capacity. Here, the
influence of the pre-straining in the deep drawing process on the force distribution
in clinch points in an automotive assembly is investigated by finite-element models
numerically. In further studies, the results are implemented in an optimization
tool for designing clinched components. The methodology starts with a pre-straining
of metal sheets. This step is followed by 2D rotationally symmetric forming simulations
of the joining process. The resulting mesh of each forming simulation is rotated
and 3D models are obtained. The clinched joint solid model with pre-strains is
used further to determine the joint stiffnesses. With the simulation of the same
test set-up with an equivalent point-connector model, the equivalent stiffness
for each pre-strain combination is determined. Simulations are performed on a
clinched component to assess the influence of pre-strain and sheet thinning on
the clinched joint loadings by using the equivalent stiffnesses. The investigations
clearly show that for the selected component, the loadings at the clinch points
are dependent on the sheet thinning and the stiffnesses due to pre-strain. The
magnitude of the influence varies depending on the quantity considered. For example,
the shear force is more sensitive to the joint stiffness than to the sheet thinning.

text: In clinching, the combinations of requirements, materials, component dimensions
and tools influence the resulting joint geometry and the resulting bonding mechanisms.
These in turn affect the property profile of the joint. For example, it is possible
to use different tools to flexibly adapt clinching points to the respective required
load regime. Clinching points dimensioned in this way can be geometrically similar,
but have different mechanical stress states, which leads to different properties
in terms of load-bearing behavior. Within the scope of this work, the clinching
process with different tools in optimal and compromise design and its effect on
the force and form-closure component, is investigated in a torsion test of the
clinched connection. Clinched steel sheets with two thicknesses and joining directions
are analyzed. Virtual experiments are carried out using finite element analyses
(FEA) of the joining process and are followed by a springback simulation. Subsequently,
the surface pressure between the two joining partners in the clinching points
is calculated on the basis of the results from the FEA and the transmittable moment
of the connection, as an indicator for the force-closure component, is determined.
Finally, the experimental and simulated data are compared and discussed.

text: Nowadays, the production of modern lightweight structures, like a body in
white structure requires a wide variety of mechanical joining processes. To fulfill
the various demands, mechanical joining processes and joining elements (JE) are
used. Very often, they are adapted to the application, which leads in turn to
a numerous of different variants, high costs, and loss of the process chain versatility.
To overcome this drawback, an innovative approach is the usage of individually
produced and task-adapted JE, the so-called friction spun joint connectors (FSJC).
These connectors can be modified in shape as well as in material properties. This
flexibility offers high potential for lightweight design but also increases the
necessary analytical effort regarding the forming process as well as the manufactured
joint's properties. Therefore, a new analysis strategy based on the Finite-Element-Method
(FEM) is proposed, which numerically determines the local load bearing capacity
within a given joint in order to identify the critical regions for load transfer.
The process of joining element manufacturing and the analysis strategy will be
described in detail and optimization results of the joints are shown. Numerical
results are discussed and possible recommendations for joint manufacturing are
derived.
