text: This paper investigates two modeling approaches for the simulation of the
deformation and decomposition behavior of preconsolidated rovings above the thermoplastic
matrix{\textquoteright} melting temperature. This is crucial for capturing the
local material structure after processes introducing highly localized deformation
such as mechanical joining processes between metal and fiber reinforced thermoplastics
(FRTP). A generic finite element (FE) model is developed, incorporating interfaces
discretized through either cohesive zone (CZ) elements or Coulomb friction-based
contacts. The material parameters for the FE elements are derived from the initial
stiffness of a statistical volume element (SVE) at micro scale modelled with an
Arbitrary-Lagrange-Eulerian method for three load cases. The CZ properties calculated
are based on the shear viscosity of the composite. The CZ and contact modelling
approaches are evaluated using three load cases of the SVE, comparing force-displacement
curves. Under simple loading conditions, such as normal pressure tension and bending,
both methods produce similar results; however, in complex load cases, the CZ approach
shows clear advantages in handling interface interactions and shows robust simulations.
The CZ approach thus presents a promising method for simulating roving decomposition
in FRTP-metal joining applications above the matrix{\textquoteright} melting temperature.

text: The failure behavior of fiber reinforced polymers (FRP) is strongly influenced
by their microstructure, i.e. fiber arrangement or local fiber volume content.
However, this information cannot be directly used for structural analyses, since
it requires a discretization on micrometer level. Therefore, current failure theories
do not directly account for such effects, but describe the behavior averaged over
an entire specimen. This foundation in experimentally accessible loading conditions
leads to purely theory based extension to more complex stress states without direct
validation possibilities. This work aims at leveraging micro-scale simulations
to obtain failure information under arbitrary loading conditions. The results
are propagated to the meso-scale, enabling efficient structural analyses, by means
of machine learning (ML). It is shown that the ML model is capable of correctly
assessing previously unseen stress states and therefore poses an efficient tool
of exploiting information from the micro-scale in larger simulations.

text: The use of continuous fiber-reinforced thermoplastics (FRTP) in automotive
industry increases due to their excellent material properties and possibility
of rapid processing. The scale spanning heterogeneity of their material structure
and its influence on the material behavior, however, presents significant challenges
for most joining technologies, such as self-piercing riveting (SPR). During mechanical
joining, the material structure is significantly altered within and around the
joining zone, heavily influencing the material behavior. A comprehensive understanding
of the underlying phenomena of material alteration during the SPR process is essential
as basis for validating numerical simulations. This study examines the material
structure at ten stages of a step-setting test of SPR with two FRTP sheets with
glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage
phenomena within different areas of the setting test are analyzed three-dimensionally
and key parameters are quantified. Dominating phenomena during the penetration
of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF)
and fiber bending, while delamination, fiber kinking and roving splitting are
also observed. At the final stages, the bottom layers of the second sheet collapse
and form a bulge into the cavity of the die.

text: A numerical modelling strategy for the direct pin pressing process
of metallic pins into continuous fibre-reinforced thermoplastic organosheets is
developed. The joining process is performed above the thermoplast’s melting temperature,
altering the initial material structure of the composite by fibre rearrangement,
which in turn influences the load-bearing capacity of the joint. Therefore, the
modelling strategy aims at predicting the resultant material structure after pin
pressing. The modelling approach considers both the textile architecture and the
process parameters (temperature, tool velocity). A sub-meso modelling framework
for the fibres based on a multi-filament approach is used. The interaction between
fibres and the thermoplastic melt, as well as the matrix flow, is modelled using
the Arbitrary Lagrangian Eulerian method. This allows for the prediction of matrix-rich
zones and fibre rearrangement around the pin. The promising results show a good
agreement of the resultant material structure in terms of compaction and fibre
volume content around the pressed pin. Characteristic parameters show an underestimation
of the laminate thickness below the pin. Moreover, an evaluation method for evaluating
the orientation changes of the virtual multi-filaments is developed and presented
to observe and assess fibre rearrangement and fibre volume content in detail during
the numerical process simulation. It can be seen that only fibres around the pin
are displaced and not in the whole molten area. Furthermore, it can be observed
in detail that the initial position of the fibres in relation to the pin determines
whether the fibres are displaced in the in-plane or out-of-plane direction.

text: 'Fiber reinforced plastics (FRP) exhibit strongly non-linear deformation behavior.
To capture this in simulations, intricate models with a variety of parameters
are typically used. The identification of values for such parameters is highly
challenging and requires in depth understanding of the model itself. Machine learning
(ML) is a promising approach for alleviating this challenge by directly predicting
parameters based on experimental results. So far, this works mostly for purely
artificial data. In this work, two approaches to generalize to experimental data
are investigated: a sequential approach, leveraging understanding of the constitutive
model and a direct, purely data driven approach. This is exemplary carried out
for a highly non-linear strain rate dependent constitutive model for the shear
behavior of FRP.The sequential model is found to work better on both artificial
and experimental data. It is capable of extracting well suited parameters from
the artificial data under realistic conditions. For the experimental data, the
model performance depends on the composition of the experimental curves, varying
between excellently suiting and reasonable predictions. Taking the expert knowledge
into account for ML-model training led to far better results than the purely data
driven approach. Robustifying the model predictions on experimental data promises
further improvement. '

text: 'Thermoplastic composites (TPCs) are predestined for use in lightweight structures,
especially for high-volume applications. In many cases, joining is a key factor
for the successful application of TPCs in multi-material systems. Many joining
processes for this material group are based on warm forming the joining zone.
This results in a change of the local material structure characterised by modified
fibre paths, as well as varying fibre contents, which significantly influences
the load-bearing behaviour. During the forming process, many different phenomena
occur simultaneously at different scales. In this paper, the deformation modes
and flow mechanisms of TPCs during forming described in the literature are first
analysed. Based on this, three different joining processes are investigated: embedding
of inserts, moulding of contour joints, and hotclinching. In order to identify
the phenomena occurring in each process and to describe the characteristic resulting
material structure in the joining zones, micrographs as well as computed tomography
(CT) analyses are performed for both individual process stages and final joining
zones.'

text: Deformation of continuous fibre reinforced plastics during thermally-assisted
forming or joining processes leads to a change of the initial material structure.
The load behaviour of composite parts strongly depends on the resultant material
structure. The prediction of this material structure is a challenging task and
requires a deep knowledge of the material behaviour above melting temperature
and the occurring complex forming phenomena. Through this knowledge, the optimisation
of manufacturing parameters for a more efficient and reproducible process can
be enabled and are in the focus of many investigations. In the present paper,
a simplified pultrusion test rig is developed and presented to investigate the
deformation behaviour of a thermoplastic semi-finished fiber product in a forming
element. Therefore, different process parameters, like forming element temperature,
pulling velocity as well as the forming element geometry, are varied. The deformation
behaviour in the forming zone of the thermoplastic preimpregnated continuous glass
fibre-reinforced material is investigated by computed tomography and the resultant
pulling forces are measured. The results clearly show the correlation between
the forming element temperature and the resulting forces due to a change in the
viscosity of the thermoplastic matrix and the resulting fiber matrix interaction.
In addition, the evaluation of the measurement data shows which forming forces
are required to change the shape of the thermoplastic unidirectional material
with a rectangular cross-section to a round one.

text: 'The paper presents research regarding a thermally supported multi-material
clinching process (hotclinching) for metal and thermoplastic composite (TPC) sheets:
an experimental approach to investigate the flow pressing phenomena during joining.
Therefore, an experimental setup is developed to compress the TPC-specimens in
out-of-plane direction with different initial TPC thicknesses and varying temperature
levels. The deformed specimens are analyzed with computed tomography to investigate
the resultant inner material structure at different compaction levels. The results
are compared in terms of force-compaction-curves and occurring phenomena during
compaction. The change of the material structure is characterized by sliding phenomena
and crack initiation and growth.'

text: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'

text: A virtual test setup for investigating single fibres in a transverse shear
flow based on a parallel-plate rheometer is presented. The investigations are
carried out to verify a numerical representation of the fluid–structure interaction
(FSI), where Arbitrary Lagrangian–Eulerian (ALE) and computational fluid dynamics
(CFD) methods are used and evaluated. Both are suitable to simulate flexible solid
structures in a transverse shear flow. Comparative investigations with different
model setups and increasing complexity are presented. It is shown, that the CFD
method with an interface-based coupling approach is not capable of handling small
fibre diameters in comparison to large fluid domains due to mesh dependencies
at the interface definitions. The ALE method is more suited for this task since
fibres are embedded without any mesh restrictions. Element types beam, solid,
and discrete are considered for fibre modelling. It is shown that the beam formulation
for ALE and 3D solid elements for the CFD method are the preferred options.

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: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'

text: Clinching continuous fibre reinforced thermoplastic composites and metals
is challenging due to the low ductility of the composite material. Therefore,
a number of novel clinching technologies has been developed specifically for these
material combinations. A systematic overview of these advanced clinching methods
is given in the present paper. With a focus on process design, three selected
clinching methods suitable for different joining tasks are described in detail.
The clinching processes including equipment and tools, observed process phenomena
and the resultant material structure are compared. Process phenomena during joining
are explained in general and compared using computed tomography and micrograph
images for each process. In addition the load bearing behaviour and the corresponding
failure mechanisms are investigated by means of single-lap shear tests. Finally,
the new joining technologies are discussed regarding application relevant criteria.
