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: Since the application of mechanical joining methods, such as clinching or
riveting, offers a robust solution for the generation of advanced multi-material
connections, the use in the field of lightweight designs (e.g. automotive industry)
is steadily increasing. Therefore, not only the design of an individual joint
is required but also the dimensioning of the entire joining connection is crucial.
However, in comparison to thermal joining techniques, such as spot welding, the
evaluation of the joints’ resistance against defined requirements (e.g. types
of load, minimal amount of load cycles) mainly relies on the consideration of
expert knowledge, a few design principles and a small amount of experimental data.
Since this generally implies the involvement of several domains, such as the material
characterization or the part design, a tremendous amount of data and knowledge
is separately generated for a certain dimensioning process. Nevertheless, the
lack of formalization and standardization in representing the gained knowledge
leads to a difficult and inconsistent reuse, sharing or searching of already existing
information. Thus, this contribution presents a specific ontology for the provision
of cross-domain knowledge about mechanical joining processes and highlights two
potential use cases of this ontology in the design of clinched and pin joints.

text: The application of the mechanical joining process clinching enables the joining
of sheet metals with a wide range of material-thickness configurations, which
is of interest in lightweight construction of multi-material structures. Each
material-thickness combination results in a joint with its own property profile
that is affected differently by variations. Manufacturing process-related effects
from preforming steps influence the geometric shape of a clinched joint as well
as its load-bearing capacity. During the clinching process high degrees of plastic
strain, increased temperatures and high strain rates occur. In this context, a
3D numerical model was developed which can represent the material-specific behaviour
during the process chain steps sheet metal forming, joining, and loading phase
in order to achieve a high predictive accuracy of the simulation. Besides to the
investigation of the prediction accuracy, the extent of the influence of individual
modelling aspects such as temperature and strain rate dependency is examined.

text: Clinching as a mechanical joining process has become established
in many areas of car body. In order to predict relevant properties of clinched
joints and to ensure the reliability of the process, it is numerically simulated
during the product development process. The prediction accuracy of the simulated
process depends on the implemented friction model. Therefore, a new method for
determining friction coefficients in sheet metal materials was developed and tested.
The aim of this study is the numerical investigation of this experimental method
by means of FE simulation. The experimental setup is modelled in a 3D numerical
simulation taking into account the process parameters varying in the experiment,
such as geometric properties, contact pressure and contact velocity. Furthermore,
the contact description of the model is calibrated via the experimentally determined
friction coefficients according to clinch-relevant parameter space. It is shown
that the assumptions made in the determination of the experimental data in preliminary
work are valid. In addition, it is investigated to what extent the standard Coulomb
friction model in the FEM can reproduce the results of the experimental method.

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 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: AbstractIn order to reduce fuel consumption
and thus pollutant emissions, the automotive industry is increasingly developing
lightweight construction concepts that are accompanied by an increasing usage
of aluminum materials. Due to poor weldability of aluminum in combination with
other materials, mechanical joining methods such as clinching were developed and
established in series production. In order to predict the relevant characteristics
of clinched joints and to ensure the reliability of the process, it is simulated
numerically during product development processes. In this regard, the predictive
accuracy of the simulated process highly depends on the implemented friction model.
In particular, the frictional behavior between the sheet metals as well as between
the sheet metal and clinching tools has a significant impact on the geometrical
formation of the clinched joint. No testing methods exist that can sufficiently
investigate the frictional behavior in sheet materials, especially under high
interface pressures, different relative velocities, and long friction paths, while
allowing a decoupled consideration of the test parameters. This paper describes
the development of further testing concepts based on a proven tribo-torsion test
method for determining friction coefficients between sheet metal materials for
the simulation of clinching processes. For this purpose, the correlation of interface
pressure and the relative velocity between aluminum and steel sheet material in
clinching processes is investigated using numerical simulation. Based on these
findings, the developed concepts focus on determining friction coefficients at
interface pressures of the above materials, yield stress, as well as the reproduction
of the occurring friction conditions between sheet metal materials and tool surfaces
in clinching processes using tool substitutes. Furthermore, wear investigations
between sheet metal material and tool surface were carried out in the friction
tests with subsequent EDX analyses of the frictioned tool surfaces. The developed
method also allows an optical deformation measurement of the sheet metal material
specimen by means of digital image correlation (DIC). Based on a methodological
approach, the test setups and the test systems used are explained, and the functionality
of the concepts is proven by experimental tests using different sheet metal materials.

text: Driven by the CO2-emission law by the European government and the increasing
costs for raw materials as well as energy, the automotive industry is increasingly
using multi-material constructions. This leads to a continuous increase in the
use of mechanical joining techniques and especially the self-piercing riveting
is of particular importance. The reason for this is the wide range of joining
possibilities as well as the high load-bearing capacities of the joints. To be
able to react to changing boundary conditions, like material thickness or strength
variation of the sheets, research work is crucial with regard to the increase
of versatility. In this paper, a numerical study of the influences on the selfpiercing
riveting process is presented. For this purpose, the influence of different process
parameters such as rivet length and die depth on various quality-relevant characteristics
were investigated. With the help of the design of experiment, significant influences
were determined and interactions between the individual parameters are shown.

text: The predictive quality of numerical simulations for mechanical joining processes
depends on the implemented material model, especially regarding the plasticity
of the joining parts. Therefore, experimental material characterization processes
are conducted to determine the material properties of sheet metal and generate
flow curves. In this regard, there are a number of procedures which are accompanied
by varying experimental efforts. This paper presents various methods of determining
flow curves for HCT590X as well as EN AW-6014, including varying specimen geometries
and diverse hardening laws for extrapolation procedures. The flow curves thus
generated are compared considering the variety of plastic strains occurring in
mechanical joining processes. The material data generated are implemented in simulation
models for the joining technologies, clinching and self-piercing riveting. The
influence of the varied methods on the predictive accuracy of the simulation model
is analysed. The evaluation of the differing flow curves is achieved by comparing
the geometric formation of the joints and the required joining forces of the processes
with experimentally investigated joints.

- description: "In many areas of product manufacturing individual components are
usually joined together to form complex structures with numerous joints. Mechanical
joining technology offers the possibility of joining structures with a wide
range of material-geometry combinations. In order to realize the increasing
number of varying products using different materials and designs within a process
chain, they need to be versatile.\r\n\r\nDue to changing properties of the materials
to be joined, tool geometries and process variables in mechanical joining processes,
especially clinching, must be continuously adapted which results in a limited
versatility of the process. In this regard, it is necessary to examine the robustness
of the clinching process in versatile process chains. Therefore, a method is
developed which describes the joint characteristics based on the material properties
in order to enable the investigation of the clinching process regarding the
robustness concerning continuously changing process and material conditions.\r\n\r\nThe
predictive accuracy of numerical simulations for mechanical joining processes
depends on the implemented material model, especially the plasticity of the
joining parts. Therefore, experimental material characterization processes are
used to determine material properties. Furthermore, clinched joints in different
material combinations are experimentally generated and examined. Based on these
investigations a simulation model of the joining process is developed as 2D-Clinching
FEM model in LS-Dyna. The Validation of the developed simulation model is ensured
by comparing the geometric formation of the joint and force-displacement curves
of the joining process with experimental generated joints. By combining the
simulation model with an optimization tool (LS-OPT) the influence of different
parameters on the joint characteristics is determined and the robustness of
the joining process in versatile process chains is investigated."
