text: In order to reduce the fuel consumption and consequently the greenhouse emissions,
the automotive industry is implementing lightweight constructions in the body
in white production. As a result, the use of aluminum alloys is continuously increasing.
Due to poor weldability of aluminum in combination with other materials, mechanical
joining technologies like clinching are increasingly used. In order to predict
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 affects the geometrical formation of the clinched joint significantly.
This paper presents a testing method, which enables to determine the frictional
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 sheets in clinching processes is investigated using numerical
simulation. Furthermore, the developed testing method focuses on the specimen
geometry as well as the reproduction of the occurring friction conditions between
two sheet metal materials in clinching processes. Based on a methodical approach
the test setup is explained and the functionality of the method is proven by experimental
tests using sheet metal material EN AW6014.

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.

text: The increasing use of multi-material constructions lead to a continuous increase
in the use of mechanical joining techniques due to the wide range of joining possibilities
as well as the high load-bearing capacities of the joints. Nevertheless, the currently
rigid tool systems are not able to react to changing boundary conditions, like
changing the material-geometry-combination. Therefore research work is crucial
with regard to versatile joining systems. In this paper, a new approach for a
versatile self-piercing riveting process considering the joining system as well
as the auxiliary joining part is presented.

text: When joining lightweight parts of various materials, clinching is
a cost efficient solution. In a production line, the quality of a clinch point
is primarily controlled by measurement of dimensions, which are accessible from
outside. However, methods such as visual testing and measuring the bottom thickness
as well as the outer diameter are not able to deliver any information about the
most significant geometrical characteristic of the clinch point, neck thickness
and undercut. Furthermore, ex-situ destructive methods such as microsectioning
cannot detect elastic deformations and cracks that close after unloading. In order
to exceed the current limits, a new non-destructive in-situ testing method for
the clinching process is necessary. This work proposes a concept to characterize
clinch points in-situ by combining two complementary non-destructive methods,
namely, computed tomography (CT) and ultrasonic testing. Firstly, clinch points
with different geometrical characteristics are analysed experimentally using ex-situ
CT to get a highly spatially resolved 3D-image of the object. In this context,
highly X-ray attenuating materials enhancing the visibility of the sheet-sheet
interface are investigated. Secondly, the test specimens are modelled using finite
element method (FEM) and a transient dynamic analysis (TDA) is conducted to study
the effect of the geometrical differences on the deformation energy and to qualify
the TDA as a fast in-situ non-destructive method for characterizing clinch points
at high temporal resolution.

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: As lightweight design gains more and more attention, time and cost-efficient
joining methods such as clinching are becoming more popular. A clinch point’s
quality is usually determined by ex situ destructive analyses such as microsectioning.
However, these methods do not yield the detection of phenomena occurring during
loading such as elastic deformations and cracks that close after unloading. Alternatively,
in situ computed tomography (in situ CT) can be used to investigate the loading
process of clinch points. In this paper, a method for in situ CT analysis of a
single-lap shear test with clinched metal sheets is presented at the example of
a clinched joint with two 2 mm thick aluminum sheets. Furthermore, the potential
of this method to validate numerical simulations is shown. Since the sheets’ surfaces
are locally in contact with each other, the interface between both aluminum sheets
and therefore the exact contour of the joining partners is difficult to identify
in CT analyses. To compensate for this, the application of copper varnish between
the sheets is investigated. The best in situ CT results are achieved with both
sheets treated. It showed that with this treatment, in situ CT is suitable to
properly observe the three-dimensional deformation behavior and to identify the
failure modes.

text: In lightweight design, clinching is a cost-efficient solution as the
joint is created through localized cold-forming of the joining parts. A clinch
point’s quality is usually assessed using ex-situ destructive testing methods.
These, however, are unable to detect phenomena immediately during the joining
process. For instance, elastic deformations reverse and cracks close after unloading.
In-situ methods such as the force-displacement evaluation are used to control
a clinching process, though deviations in the clinch point geometry cannot be
derived with this method. To overcome these limitations, the clinching process
can be investigated using in-situ computed tomography (in-situ CT). However, a
clinching tool made of steel would cause strong artefacts and a high attenuation
in the CT measurement, reducing the significance of this method. Additionally,
when joining parts of the same material, the sheet-sheet interface is hardly detectable.
This work aims at identifying, firstly, tool materials that allow artefact-reduced
CT measurements during clinching, and, secondly, radiopaque materials that can
be applied between the joining parts to enhance the detectability of the sheet-sheet
interface. Therefore, both CT-suitable tool materials and radiopaque materials
are selected and experimentally investigated. In the clinching process, two aluminium
sheets with radiopaque material in between are clinched in a single-step (rotationally
symmetric joint without cut section). It is shown that e.g. silicon nitride is
suited as tool material and a tin layer is suitable to enhance the detectability
of the sheet-sheet interface.

text: Self-piercing riveting is an established technique for joining multi-material
structures in car body manufacturing. Rivets for self-piercing riveting differ
in their geometry, the material used, the condition of the material and their
surface condition. To shorten the manufacturing process by omitting the heat treatment
and the coating process, the authors have elaborated a concept for the use of
stainless steel with high strain hardening as a rivet material. The focus of the
present investigation is on the evaluation of the influences of the rivet’s geometry
and material on its deformation behaviour. Conventional rivets of types P and
HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets
made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted
by means of multi-step joining tests for two material combinations comprising
high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide
a cross-section and the deformation behaviour of the different rivets is analysed
on the basis of the measured changes in geometry and hardness. In parallel, an
examination of the force-stroke curves provides further insights. It can be demonstrated
that, besides the geometry, the material strength, in particular, has a significant
influence on the deformation behaviour of the rivet. The strength of steel 1.4541
is seen to be too low for the joining task, while the strength of steel 1.3815
is sufficient, and hence the investigation confirms the capability of rivets made
of 1.3815 for joining even challenging material combinations.

text: 'The use of high-strength steel and aluminium is rising due to the intensified
efforts being made in lightweight design, and self-piercing riveting is becoming
increasingly important. Conventional rivets for self-piercing riveting differ
in their geometry, the material used, the condition of the material and the coating.
To shorten the manufacturing process, the use of stainless steel with high strain
hardening as the rivet material represents a promising approach. This allows the
coating of the rivets to be omitted due to the corrosion resistance of the material
and, since the strength of the stainless steel is achieved by cold forming, heat
treatment is no longer required. In addition, it is possible to adjust the local
strength within the rivet. Because of that, the authors have elaborated a concept
for using high nitrogen steel 1.3815 as the rivet material. The present investigation
focusses on the joint strength in order to evaluate the capability of rivets in
high nitrogen steel by comparison to conventional rivets made of treatable steel.
Due to certain challenges in the forming process of the high nitrogen steel rivets,
deviations result from the targeted rivet geometry. Mainly these deviations cause
a lower joint strength with these rivets, which is, however, adequate. All in
all, the capability of the new rivet is proven by the results of this investigation. '
