  text: <jats:p>Friction-spinning is an incremental thermomechanical forming process
    that has huge potential due to its simple yet effective mechanism of utilising
    friction between a rotating workpiece and a forming tool to increase the workpiece’s
    temperature, which reduces the required forces and increases formability during
    the forming process. Despite the simplicity of the process’s setup, the thermomechanical
    loads and high relative velocities involved, especially in the contact zone, make
    the application of classical methods for characterising friction inaccurate. It
    is therefore essential to find a way to describe the frictional behaviour under
    real process conditions to be able to gain a holistic understanding of the process
    and the effect of the adjustable parameters on the outcome, especially the temperature.
    To achieve this goal, an experimental setup that considers the actual process
    boundary conditions in forming tubes made of EN AW-6060 was used to measure in
    situ normal and frictional forces, in addition to process temperatures, under
    varying rotational speed and feed rate values.</jats:p>

  text: <jats:p>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.</jats:p>

  text: <jats:p>Multi-material designs (MMD) are more frequently used in the automotive
    industry. Hereby, the combination of different materials, metal sheets, or cast
    components, is mechanically joined, often by forming joining processes. The cast
    components mostly used are high-strength, age-hardenable aluminium alloys of the
    Al–Si system. Here, the low ductility of the AlSi alloys constitutes a challenge
    because their brittle nature causes cracks during the joining process. However,
    by using suitable solidification conditions, it is possible to achieve a microstructure
    with improved mechanical and joining properties. For this study, we used the twin-roll
    casting process (TRC) with water-cooled rollers to manufacture the hypoeutectic
    AlSi10Mg for the first time. Hereby, high solidification rates are realisable,
    which introduces a microstructure that is about four times finer than in the sand
    casting process. In particular, it is shown that a fine microstructure close to
    the modification with Na or Sr is achieved by the high solidification rate in
    the TRC process without using these elements. Based on this, the mechanical properties
    increase, and especially the ductility is enhanced. Subsequent joining investigations
    validate the positive influence of a high solidification rate since cracks in
    joints can be avoided. Finally, a microstructure-property-joint suitability correlation
    is presented.</jats:p>

  text: <jats:p>Consistent lightweight construction in the area of vehicle manufacturing
    requires the increased use of multi-material combinations. This, in turn, requires
    an adaptation of standard joining techniques. In multi-material combinations,
    the importance of integral cast components, in particular, is increasing and poses
    additional technical challenges for the industry. One approach to solve these
    challenges is adaptable joining elements manufactured by a thermomechanical forming
    process. By applying an incremental and thermomechanical joining process, it is
    possible to react immediately and adapt the joining process inline to reduce the
    number of different joining elements. In the investigation described in this publication,
    cast plates made of the cast aluminium alloy EN AC-AlSi9 serve as joining partners,
    which are processed by sand casting. The joining process of hypoeutectic AlSi
    alloys is challenging as their brittle character leads to cracks in the joint
    during conventional mechanical joining. To solve this, the frictional heat of
    the novel joining process applied can provide a finer microstructure in the hypoeutectic
    AlSi9 cast alloy. In detail, its Si is finer-grained, resulting in higher ductility
    of the joint. This study reveals the thermomechanical joining suitability of a
    hypoeutectic cast aluminium alloy in combination with adaptively manufactured
    auxiliary joining elements.</jats:p>

  text: <jats:p>The pressure fields generated by two simultaneous discharges have
    not been investigated on any notable scale for the electrohydraulic impulse forming
    method. In this study, the synchronicity of two discharges is ensured by the sequential
    connection of two wires mounted in two spark gaps in a common volume of liquid.
    The objective is to experimentally confirm the equilibrium of the energies evolved
    in two spark gaps by means of pressure measurements. In addition, multipoint membrane
    pressure gauges demonstrated the feasibility of easily recording detailed pressure
    maps. Based on the membrane deformation mechanism and material strengthening under
    static and impulse conditions, the processing procedure is further developed so
    as to achieve better accuracy in the determination of pressure field parameters.
    The practical equality of the pressure fields on the left and right halves of
    the flat-loaded area confirms the equality of energies evolved in the two spark
    gaps. The direct shock waves create zones with the most intensive loading. These
    results provide a basis for the development of new electrohydraulic technologies
    involving the application of two simultaneous discharges with equal energy and
    pressure parameters.</jats:p>

  text: <jats:p>The demands on joining technology are constantly increasing due to
    the consistent lightweight construction and the associated increasing material
    mix. To meet these requirements, the adaptability of the joining processes must
    be improved to be able to process different material combinations and to react
    to challenges caused by deviations in the process chain. One example of a highly
    adaptable process due to the two-step process sequence is thermomechanical joining
    with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to
    the joint. In this paper, the potentials of the adaption in the two-stage joining
    process with aluminium auxiliary joining elements are investigated. To this end,
    it is first investigated whether a thermomechanical forming process can be used
    to achieve a uniform and controlled manufacturing regarding the process variable
    of the temperature as well as the geometry of the FSJC. Based on the successful
    proof of the high and good repeatability in the FSJC manufacturing, possibilities,
    and potentials for the targeted influencing of the process and FSJC geometry are
    shown, based on an extensive variation of the process input variables (delivery
    condition and thus mechanical properties of the raw parts as well as the process
    parameters of rotational speed and feed rate). Here it can be shown that above
    all, the feed rate of the final forming process has the strongest influence on
    the process and thus also offers the strongest possibilities for influencing it.</jats:p>

  text: The sustainability of the manufacturing industry is of special importance
    to increase the protection of the environment. The production of fasteners like
    self-piercing rivets, however, is costly, time-consuming and energy-intensive.
    The heat treatment and the coating, which are mandatory in conventional self-piercing
    rivets to achieve adequate strength, ductility and corrosion resistance, are especially
    crucial in this respect. Within this paper, an approach for an increase in the
    sustainability in fastener production is presented. The use of alternative, high
    strain hardening stainless steels as rivet material enables a shortening of the
    process chain, because post treatment of the rivets after they are formed can
    be omitted. As the change in rivet material and processing causes some issues
    along the process chain, the focus of this paper is on the holistic evaluation
    of the challenges within the forming of high strain hardening steel and the impact
    of the changed rivet properties on the joining result.

  text: The trend towards lightweight design, driven by increasingly stringent emission
    targets, poses challenges to conventional joining processes due to the different
    mechanical properties of the joining partners used to manufacture multi-material
    systems. For this reason, new versatile joining processes are in demand for joining
    dissimilar materials. In this regard, pin joining with cold extruded pin structures
    is a relatively new, two-stage joining process for joining materials such as high-strength
    steel and aluminium as well as steel and fibre-reinforced plastic to multi-material
    systems, without the need for auxiliary elements. Due to the novelty of the process,
    there are currently only a few studies on the robustness of this joining process
    available. Thus, limited statements on the stability of the joining process considering
    uncertain process conditions, such as varying material properties or friction
    values, can be provided. Motivated by this, the presented work investigates the
    influence of different uncertain process parameters on the pin extrusion as well
    as on the joining process itself, carrying out a systematic robustness analysis.
    Therefore, the methodical approach covers the complete process chain of pin joining,
    including the load-bearing capacity of the joint by means of numerical simulation
    and data-driven methods. Thereby, a deeper understanding of the pin joining process
    is generated and the versatility of the novel joining process is increased. Additionally,
    the provision of manufacturing recommendations for the forming of pin joints leads
    to a significant decrease in the failure probability caused by ploughing or buckling
    effects.

  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: Pin extrusion is a common process to realise pin structures in different geometrical
    dimensions for a subsequent joining operation. Nevertheless, the process of pin
    extrusion offers process limits regarding sheet thinning as a consequence of the
    punch penetration depth into the sheet. Thereby, cracks at the residual sheet
    thickness can occur during strength tests, resulting in a failure of the complete
    joint due to severe thinning. Therefore, measures have to be taken into account
    to reduce the thinning. One possibility is the application of orbital formed tailored
    blanks with a local material pre-distribution, which allows a higher sheet thickness
    in the desired area. Within this contribution, the novel approach of a process
    combination of orbital forming and pin extrusion is investigated. To reveal the
    potential of a local material pre-distribution, conventional specimens are compared
    with previously orbital formed components. Relevant parameters such as the residual
    sheet thickness, the pin height as well as the average hardness values are compared.
    The results show a significant positive influence of a local material pre-distribution
    on the residual sheet thickness as well as the resulting pin height. Furthermore,
    the strain hardening during orbital forming can be seen as an additional advantage.
    To conclude the results, the process limits of conventional pin extrusion can
    be expanded significantly by the application of specimens with a local material
    pre-distribution.
