text: AbstractThe constantly increasing challenges
of production technology for the economic and resource-saving production of metallic
workpieces require, among other things, the optimisation of existing processes.
Forming technology, which is confronted with new challenges regarding the quality
of the workpieces, must also organise the individual processes more efficiently
and at the same time more reliably in order to be able to guarantee good workpiece
quality and at the same time to be able to produce economically. One way to meet
these challenges is to carry out the forming processes in closed-loop control
systems using softsensors. Despite the many potential applications of softsensors
in the field of forming technology, there is still no definition of the term softsensor.
This publication therefore proposes a definition of the softsensor based on the
definition of a sensor and the distinction from the observer, which on the one
hand is intended to stimulate scientific discourse and on the other hand is also
intended to form the basis for further scientific work. Based on this definition,
a wide variety of highly topical application examples of various softsensors in
the field of forming technology are given.

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: The use of mechanical joining technologies offers the possibility of joining
mixed material structures, which are used in particular in lightweight construction.
An integrated securing of the joinability in versatile process chains is currently
hardly possible as the number of combinable tool variants as well as variable
force- and path-based process parameters is infinite. A versatile process chain,
i.e. a sequence of all the processes and process steps required for product manufacturing,
enables targeted changes to the semi-finished product, the joint, the component
or the joining process that exceed the originally planned extend while still ensuring
joinability. In detail, it leads to a unique joint with its own mechanical property
profile, which, against the background of the resulting infinite number of combinations,
makes it impossible to secure the joinability on the conventional experimentally
based approach without extensive safety factors. The Transregional Colaborative
Research Center 285 (TCRC285), which also initiated this special issue, is intended
to enable mechanical joining technology to be versatile in the sense of high application
flexibility. This is to be achieved with a numerical representation of the complete
process chain from the incoming semi finished product via the joining part production
and the joining process to the property profile of the joint in the operating
phase. Thus a predictability of the joinability can be achieved and improvements
in the individual life cycles of a joint can be realized by grasping the cause-and-effect
relationships. On the basis of this knowledge, new possibilities for intervention
in the joining process are to be created for the adaptation of the joining processes.
With the aid of the methods developed for this purpose, tools will later be available
to the end user to substitute the large number of mechanical joining processes
or joining task-specific configurations with a smaller number of adaptable processes.
This expands the flexibility in material choices, enabling challenges in environmental
issues and sustainability to be overcome.

text: Due to the increasing use of multi-material constructions and the resulting
material incompatibilities, mechanical joining technologies are gaining in importance.
The reasons for this are the variety of joining possibilities as well as high
load-bearing capacities. However, the currently rigid tooling systems cannot react
to changing boundary conditions, such as changed sheet thicknesses or strength.
For this reason, a large number of specialised joining processes have been developed
to expand the range of applications. Using a versatile self-piercing riveting
process, multi-material structures are joined in this paper. In this process,
a modified tool actuator technology is combined with multi-range capable auxiliary
joining parts. The multi-range capability of the rivets is achieved by forming
the rivet head onto the respective thickness of the joining part combination without
creating a tooling set-up effort. The joints are investigated both experimentally
on the basis of joint formation and load-bearing capacity tests as well as by
means of numerical simulation. It turned out that all the joints examined could
be manufactured according to the defined standards. The load-bearing capacities
of the joints are comparable to those of conventionally joined joints. In some
cases the joint fails prematurely, which is why lower energy absorptions are obtained.
However, the maximum forces achieved are higher than those of conventional joints.
Especially in the case of high-strength materials arranged on the die side, the
interlock formation is low. In addition, the use of die-sided sheets requires
a large deformation of the rivet head protrusion, which leads to an increase in
stress and, as a result, to damage if the rivet head. However, a negative influence
on the joint load-bearing capacity could be excluded.

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: AbstractIn 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: 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 modern vehicle chassis, multi-material design is implemented to apply the
appropriate material for each functionality. In spaceframe technology, both sheet
metal and continuous cast are joined to castings at the nodal points of the chassis.
Since resistance spot welding is not an option when different materials are joined,
research is focusing on mechanical joining methods for multi-material designs.
To reduce weight and achieve the required strength, hardenable cast aluminium
alloys of the AlSi-system are widely used. Thus, 85–90% of aluminium castings
in the automotive industry are comprised of the AlSi-system. Due to the limited
weldability, mechanical joining is a suitable process. For this application, various
optimisation strategies are required to produce a crack-free joint, as the brittle
character of the AlSi alloy poses a challenge. Thus, adapted castings with appropriate
ductility are needed. Hence, in this study, the age-hardenable cast aluminium
alloy AlSi10Mg is investigated regarding the correlation of the different thicknesses,
the microstructural characteristics as well as the resulting mechanical properties.
A variation of the thicknesses leads to different solidification rates, which
in turn affect the microstructure formation and are decisive for the mechanical
properties of the casting as well as the joinability. For the investigation, plates
with thicknesses from 2.0 to 4.0 mm, each differing by 0.5 mm, are produced via
sand casting. Hence, the overall aim is to evaluate the joinability of AlSi10Mg
and derive conclusions concerning the microstructure and mechanical properties.

text: AbstractRecent developments in automotive
and aircraft industry towards a multi-material design pose challenges for modern
joining technologies due to different mechanical properties and material compositions
of various materials such as composites and metals. Therefore, mechanical joining
technologies like clinching are in the focus of current research activities. For
multi-material joints of metals and thermoplastic composites thermally assisted
clinching processes with advanced tool concepts are well developed. The material-specific
properties of fibre-reinforced thermoplastics have a significant influence on
the joining process and the resulting material structure in the joining zone.
For this reason, it is important to investigate these influences in detail and
to understand the phenomena occurring during the joining process. Additionally,
this provides the basis for a validation of a numerical simulation of such joining
processes. In this paper, the material structure in a joint resulting from a thermally
assisted clinching process is investigated. The joining partners are an aluminium
sheet and a thermoplastic composite (organo sheet). Using computed tomography
enables a three-dimensional investigation that allows a detailed analysis of the
phenomena in different joining stages and in the material structure of the finished
joint. Consequently, this study provides a more detailed understanding of the
material behavior of thermoplastic composites during thermally assisted clinching.

text: AbstractIn addition to the classical strength
calculation, it is important to design components with regard to fracture mechanics
because defects and cracks in a component can drastically influence its strength
or fatigue behavior. Cracks can propagate due to operational loads and consequently
lead to component failure. The fracture mechanical analysis provides information
on stable or unstable crack growth as well as about the direction and the growth
rate of a crack. For this purpose, sufficient information has to be available
about the crack location, the crack length, the component geometry, the component
loading and the fracture mechanical material parameters. The fracture mechanical
properties are determined experimentally with standardized specimens as defined
by the guidelines of the American Society for Testing and Materials. In practice,
however, especially in the context with damage cases or formed material fracture
mechanical parameters directly for a component are of interest. However, standard
specimens often cannot be extracted at all due to the complexity of the component
geometry. Therefore, the development of special specimens is required whereby
certain arrangements have to be made in advance. These arrangements are presented
in the present paper in order to contribute to a holistic investigation chain
for the experimental determination of fracture mechanical material parameters
with special specimens.

a pulsed YVO4 Laser source with a wavelength of 1064 nm and a maximum power of
25 W was utilized to increase the surface area of the steel HCT490X in order to
improve its bonding properties with a carbon fibre reinforced polymer (CFRP).
Investigated was the influence of the scanning speed of the laser source on the
bonding properties. For this purpose, the steel surfaces were ablated at a scanning
speed between 1500 and 4500 mm/s. Afterwards the components were bonded with the
adhesive HexBond™ 677. After lap shear tests were carried out on the specimen,
the surfaces were inspected using scanning electron microscopy (SEM). The experiments
revealed that the bonding quality can be improved with a high scanning speed,
even when the surface is not completely ablated.

text: AbstractRecent developments in automotive
and aircraft industry towards a multi-material design pose challenges for modern
joining technologies due to different mechanical properties and material compositions
of various materials such as composites and metals. Therefore, mechanical joining
technologies like clinching are in the focus of current research activities. For
multi-material joints of metals and thermoplastic composites thermally assisted
clinching processes with advanced tool concepts are well developed. The material-specific
properties of fibre-reinforced thermoplastics have a significant influence on
the joining process and the resulting material structure in the joining zone.
For this reason, it is important to investigate these influences in detail and
to understand the phenomena occurring during the joining process. Additionally,
this provides the basis for a validation of a numerical simulation of such joining
processes. In this paper, the material structure in a joint resulting from a thermally
assisted clinching process is investigated. The joining partners are an aluminium
sheet and a thermoplastic composite (organo sheet). Using computed tomography
enables a three-dimensional investigation that allows a detailed analysis of the
phenomena in different joining stages and in the material structure of the finished
joint. Consequently, this study provides a more detailed understanding of the
material behavior of thermoplastic composites during thermally assisted clinching.

text: "Friction-spinning is an incremental forming process, which is accompanied
by complex thermal and mechanical loads in the tool and the formed part. To influence
the process temperature, two main process parameters, i.e. the rotation speed
and the feed rate, can be adapted. With the objective to improve the tool performance
and the quality of the workpiece, this study focuses on a coating concept for
friction-spinning tools made of high speed steel (HS6 5 2C, 1.3343). On the one
hand, atmospheric plasma sprayed (APS) Al2O3 and ZrO2-8Y2O3 coatings serve as
a thermal insulator, and, on the other hand, physically vapor deposited (PVD)
TiAlSi7.9N and CrAlSi7.5N films are applied to increase the hardness and wear
resistance of the tools. In addition, duplex coatings, combining the APS and PVD
technique, are synthesized to influence both the heat transfer and the tribological
properties of friction-spinning tools.\r\nSubsequently, all coated tools are tested
in a friction-spinning process to form flanges made of AW-6060 (AlMgSi 3.3206)
tube materials. The tool temperatures are determined in-situ to investigate the
impact of the tool coating on the process temperature. Compared to an uncoated
tool, the alumina and zirconia coatings contribute to a reduction of the tool
temperature by up to half, while the PVD films increase the hardness of the tool
by 20 GPa. Furthermore, it is shown that the surface quality of thermally sprayed
(TS) or PVD coated tools is directly related to the surface roughness of the resulting
workpiece.\r\n"
