text: Focusing on upcoming challenges in lightweight design, such as increasing
emission targets or novel multimaterial connections, versatile applicable and
environmentally friendly production technologies are crucial. In this context,
mechanical joining technology clinching offers a fast and energy-efficient procedure
for assembling sheet metals, being a proper alternative to established joining
methods, such as spot welding. However, the design of clinch points is a challenge,
which is partly supported by numerical or data-based approaches for optimal tool
dimensions assuring proper joint characteristics. While this is usually done for
an ideal environment, real joining processes are characterized by multiple inevitably
varying parameters, e.g. of the material, which have a significant impact on the
quality of clinch points. Therefore, this contribution addresses the current gap
by analyzing the effect of parameter variations or uncertainties on the resulting
joint characteristics and studying the impact of the nominal tool design. Thus,
an efficient meta-model-based variation simulation procedure is proposed and used
for analyzing the effect of different tool design configurations and variation
scenarios. Based on the results, it was found that varying process parameters
have a strong impact on the resulting joint characteristics, whereby the effect
significantly depends on the nominal tool design. This reveals the potential for
a robust tool design and implies that the nominal tool design and the tolerancing
of parameters should be done simultaneously for a reliable virtual joining point
design without extensive iterations and physical tests.

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: 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: 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: Challenges in the development of resource-efficient lightweight designs, such
as emission and cost targets in production, lead to an increasing demand for environmentally
friendly and fast joining processes. Therefore, cold-forming mechanical joining
techniques provide an energy-efficient alternative in comparison to established
processes, such as spot welding. However, to ensure a sufficient reliability of
the product design, not only the selection of an appropriate manufacturing and
joining method, but also the suitable dimensioning and validation of the entire
joining process is a crucial step. In this context, thermal processes offer a
large number of design principles while mechanical joining methods mainly require
extensive experimental tests and the inclusion of expert knowledge. Although few
contributions already investigated the data-based analysis of mechanical joints,
a system for the requirement- and manufacturing-oriented dimensioning of joining
components, such as different profiles and blanks, in combination with the estimation
of joint properties is not available yet. Motivated by this lack, this contribution
introduces an engineering workbench for the support of design engineers in the
early development phases of the knowledge and data-based design of mechanical
joining connections using clinching as an example. In this regard, the approach
is demonstrated involving a similar material and sheet thickness combination with
static loads.

text: Given strict emission targets and legal requirements, especially in the automotive
industry, environmentally friendly and simultaneously versatile applicable production
technologies are gaining importance. In this regard, the use of mechanical joining
processes, such as clinching, enable assembly sheet metals to achieve strength
properties similar to those of established thermal joining technologies. However,
to guarantee a high reliability of the generated joint connection, the selection
of a best-fitting joining technology as well as the meaningful description of
individual joint properties is essential. In the context of clinching, few contributions
have to date investigated the metamodel-based estimation and optimization of joint
characteristics, such as neck or interlock thickness, by applying machine learning
and genetic algorithms. Therefore, several regression models have been trained
on varying databases and amounts of input parameters. However, if product engineers
can only provide limited data for a new joining task, such as incomplete information
on applied joining tool dimensions, previously trained metamodels often reach
their limits. This often results in a significant loss of prediction quality and
leads to increasing uncertainties and inaccuracies within the metamodel-based
design of a clinch joint connection. Motivated by this, the presented contribution
investigates different machine learning algorithms regarding their ability to
achieve a satisfying estimation accuracy on limited input data applying a statistically
based feature selection method. Through this, it is possible to identify which
regression models are suitable to predict clinch joint characteristics considering
only a minimum set of required input features. Thus, in addition to the opportunity
to decrease the training effort as well as the model complexity, the subsequent
formulation of design equations can pave the way to a more versatile application
and reuse of pretrained metamodels on varying tool configurations for a given
clinch joining task.

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: 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: "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.
