text: Die Wandlungsfähigkeit einer Prozesskette erfordert Fügeverbindungen mit gezielt
einstellbaren mechanischen, elektrischen, thermischen oder chemischen Eigenschaften.
Dieser Beitrag beschreibt die Untersuchungen, inwiefern beim Clinchen zweier Bleche
aus der ausscheidungshärtbaren Aluminiumlegierung EN AW-6014 bereits auf Basis
der Prozessüberwachung des Kraft-Weg-Verlaufs bzw. des sich daraus ergebenden
Energieeintrags auf die mechanischen und elektrischen Eigenschaften der Fügeverbindung
geschlossen werden kann. An einer ausgewählten Fügeaufgabe werden im Stufenversuch
die gegenseitigen Abhängigkeiten der einzelnen Einflussgrößen sowie des Wärmebehandlungszustands
aufgezeigt. Dabei wird zwischen den Bindemechanismen Formschluss und Kraftschluss
unterschieden. Die Formschlusskomponente wird anhand der geometrischen Kenngrößen
wie Bodendicke, Halsdicke und Hinterschnitt in Mikroskopieuntersuchungen an Schliffbildern
und den mechanischen Eigenschaften der Fügeverbindung untersucht, die im Scherzug-
und Kopfzugversuch bestimmt werden. Dazu erfolgt zudem die Charakterisierung der
Versagensbilder. Zur Quantifizierung der Kraftschlusskomponente der Fügeverbindung
werden das Losbrechmoment im Torsionsversuch und der elektrische Widerstand mittels
Vier-Leiter-Methode ermittelt und korreliert.

text: Similar to bulk metal forming, clinch joining is characterised by large plastic
deformations and a variety of different 3D stress states, including severe compression.
However, inherent to plastic forming is the nucleation and growth of defects,
whose detrimental effects on the material behaviour can be described by continuum
damage models and eventually lead to material failure. As the damage evolution
strongly depends on the stress state, a stress-state-dependent model is utilised
to correctly track the accumulation. To formulate and parameterise this model,
besides classical experiments, so-called modified punch tests are also integrated
herein to enhance the calibration of the failure model by capturing a larger range
of stress states and metal-forming-specific loading conditions. Moreover, when
highly ductile materials are considered, such as the dual-phase steel HCT590X
and the aluminium alloy EN AW-6014 T4 investigated here, strong necking and localisation
might occur prior to fracture. This can alter the stress state and affect the
actual strain at failure. This influence is captured by coupling plasticity and
damage to incorporate the damage-induced softening effect. Its relative importance
is shown by conducting inverse parameter identifications to determine damage and
failure parameters for both mentioned ductile metals based on up to 12 different
experiments.

text: Abstract. In the numerical simulation of mechanical joining technologies
such as clinching, the material modeling of the joining parts is of major importance.
This includes modeling the damage and failure behavior of the materials in accordance
with varying occurring stress states. This paper presents a calibration method
of three different fracture models. The calibration of the models is done by use
of experimental data from a modified punch test, tensile test and bulge test in
order to map the occurring stress states from clinching processes and to precisely
model the resulting failure behavior. Experimental investigations were carried
out for an aluminum alloy EN AW-6014 in temper T4 and compared with the simulative
results generated in LS-DYNA. The comparison of force-displacement curves and
failure initiation shows that the Hosford–Coulomb model predicts the failure behavior
for the material used and the tests applied with the best accuracy.

text: Monitoring force-displacement or force-time curves is a widely used quality
control technique in the field of mechanical joining. For online monitoring of
self-piercing riveting, envelope curves are often used to define a tolerance zone
for the measured setting force. However, the measurement uncertainty is typically
not considered and the force curve of a joint can be wrongly rated as non-conform
due to measurement errors and noise. In this article, we present a method for
dynamical online filtering and uncertainty determination for noisy force curves
using two types of Bayesian filters. The methodology is based on a Bayesian probability
framework using a priori information for the process curve and sensor noise. To
investigate the general feasibility of the method, force measurements with different
noise levels are simulated and processed. The conformity is further assessed taking
the uncertainty of the filtered signal into account. The results show that the
Bayes filter technique is principally able to reduce noise for well-known characteristics
of the process curve and sensor noise. Advantages over common filtering techniques,
especially for experimental conditions with less known characteristics, are still
to be verified. The methodology could be used in future for closed-loop controls
to adapt process parameters dynamically.

text: Due to economic and ecological framework conditions, a resource-saving utilization
of raw materials and energy is becoming increasingly important in particular in
the mobility sector. For the reduction of moving masses and the resources consumed,
lightweight construction technologies are part of modern production processes
in vehicle manufacturing, for example in the form of multi-material systems. Challenging
in the manufacture of multi-material systems especially in view of changing supply
chains is the variety of materials and geometries that bring conventional joining
processes to their limits. Therefore, new processes are required, which can react
versatile to process and disturbance variables. A widely used industrial joining
process is semi-tubular self-piercing riveting, which is however a rigid process.
To increase the versatility, the two newly established processes multi-range self-piercing
riveting and tumbling self-piercing riveting are combined and the capabilities
for targeted material flow control are united. Therefore, an innovative two-stage
process based on the combination is introduced in this paper. The rivet is set
with the multi-range self-piercing riveting process with an overlap of the rivet
head and then formed by a tumbling process. Further, a specific adaptation of
the tumbling strategy is used to investigate the possibility of reducing cracks
in the rivet head. Thereby, different tumbling strategies are used and similar
geometric joint formations are achieved to compare the results.

text: "Abstract. The miniaturisation of components leads to new demands on measurement
systems. One of these is the resolution. As a volumetric analysis method and method
of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has
the ability to measure geometrical features and their corresponding dimensions
without destroying them and can therefore be used for quality assurance. However,
the concept of resolution is not trivial for XCT and has not yet been finally
clarified. In particular, the interface structural resolution, the detectability
of two surfaces facing each other after surface segmentation, faces a lack of
a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based
XCT investigations of a method to determine this type of resolution are presented
in this article using the geometry of a test specimen that contains several radially\r\narranged
holes of the same size. The borehole diameters correspond to the distance between
the holes to investigate the resolvability of surfaces and interfaces. The evaluation
is based on mean and extreme values of grey value\r\nprofiles between the individual
boreholes of the reconstructed volume. It is shown that the geometrical detectability
of the test specimen surface and interface can be extended by a reasonable choice
of the threshold value for\r\nsurface segmentation within a defined interval.
With regard to the resolving capability, a distinction is made between assured
detectability and possible detectability, as well as the threshold value used
when using the ISO50\r\nthreshold for surface segmentation and measurement chain
completion. "

text: Abstract. Increasing resource efficiency is a major challenge and
affects almost every aspect of social and economic life. The mobility sector in
particular is responsible for a large share of primary energy consumption and
is increasingly in the focus of public interest. One possibility to adress these
challenges is to reduce the vehicle weight by means of lightweight construction
technologies such as multi-material systems. These assemblies consist of workpieces
with different mechanical and geometrical properties, which poses a major challenge
for joining technology. Mechanical joining processes such as semi-tubular self-piercing
riveting are often used in the production of these assemblies, but due to their
process characteristics, they are rigid and can only react to changing process
variables to a limited extent. One way to increase the versatility of self-piercing
riveting is to superimpose a tumbling kinematics on the punch. During tumbling,
an angular offset of the punch axis to the tool axis is set and the contact area
between punch and workpiece is reduced. In this work, investigations were carried
out to determine how the tumbling strategy, consisting of the parameters tumbling
angle, tumbling onset and tumbling kinematics, affects the material flow of the
rivet element. For this purpose, experimental tests are conducted with the typical
materials of conventional multi-material systems and the geometric joint formations
are determined by means of macrographs.

text: Abstract. Force-displacement measurements and macrosections are commonly
used methods to validate numerical models of clinching processes. However, these
ex-situ methods often lead to springback of elastic deformations and crack-closing
after unloading. In contrast, the in-situ computed tomography (CT) can provide
three-dimensional images of the clinching point under loading conditions. So far,
the quantity of elastic springback that causes measuring deviations between in-
and ex-situ measurements is not determined. In this paper, a method is described
to quantitatively compare the results of in-situ CT, ex-situ CT and CT scans of
cut specimens, which are prepared for macrosectioning, among each other. The method
is applied to a single-lap shear test of two clinched aluminum sheets. Here, the
test is conducted to specific process steps, then the specimen is CT scanned in-situ
(during loading) and ex-situ (after unloading). Subsequently, the specimens are
cut for macrosectioning and CT scanned. Finally, the outer contours and the interfaces
of cross section images are determined by digital image analysis and the deviations
over the clinching point between ex- and in-situ methods are calculated.

text: We contrast different gradient-enhancements for plasticity-damage material
models in the logarithmic strain space and compare them to reference models based
on multiplicative plasticity. The models being compared include plasticity - gradient-damage,
where the gradient-enhancement is applied on the local damage variable, and gradient-plasticity
- damage with a gradient-enhanced plastic hardening variable. Thereby, gradient-plasticity
proved to be able to simultaneously regularise plastic and ductile (plasticity-driven)
damage localisation as confirmed by numerical localisation analyses. This appears
to be especially advantageous for logarithmic strain space plasticity-damage,
because of the observed plastic localisation even for the case of plasticity with
hardening. Even though gradient-plasticity appears to be numerically more demanding,
two numerical examples indicate a good robustness and mesh objectivity in the
softening regime. Moreover, the internal length for plasticity is able to adjust
the damage zone width, similarly to gradient-damage, however ensuring a priori
that damage takes place exclusively inside the plastic zone.
