  text: Additive plasticity in the logarithmic strain space is compared to multiplicative
    plasticity for various loading cases including coaxial and non-coaxial plastic
    deformations. Even though both finite plasticity approaches are based on total
    Lagrangian descriptions, the former is popular due to its inherent similarity
    to the infinitesimal theory and its easy extensibility. However, since its introduction
    several limitations of additive plasticity in the logarithmic strain space have
    been discovered. In this study, these problems such as stress rotation and softening
    are considered, revealing that fundamental differences compared to multiplicative
    plasticity occur for non-coaxial plastic deformations. We focus in particular
    on the observed softer response of the additive based approach, which is analysed
    in depth using three numerical examples including two well-known benchmarks for
    finite plasticity. By means of these finite element simulations the softer and
    possibly even localising response of additive plasticity in the logarithmic strain
    space is confirmed.

  text: "Lightweight construction has increasingly become the focus of scientific
    research in recent years, not least due to\r\nthe constantly increasing fuel price,
    which is a key factor in the economic viability of many companies. In this\r\nrespect,
    the use of hybrid structures, made of dissimilar materials offers many advantages.
    However, such hybrid\r\nstructures often have undesirable side effects. For example,
    brittle intermetallic phases are formed when\r\naluminum and steel are welded.
    Clinching as a mechanical joining process does not produce such intermetallic\r\nphases
    since the connection is realized through form and force closure. In this process,
    a punch passes through\r\ntwo or more sheets and forms them into a permanent joint
    in a die. In the present work, the corrosion phenomena\r\nof an aluminum-steel
    clinched joint have been investigated by both experiments and numerical simulations
    in\r\norder to explain the superior fatigue behavior of pre-corroded joints. Therefore,
    the clinched joints have been\r\ncorroded by a three-week salt-spray test. In
    addition, the electric potential and the von Mises stress are calculated\r\nunder
    the assumption of a static loading. The results of both experiments and numerical
    simulations can explain\r\nthe improvement in the fatigue behavior of the corroded
    specimens. This phenomenon can be attributed to the\r\naccumulation of corrosion
    products in small gaps between the joined metal sheets."

  text: Clinching is the manufacturing process of joining two or more metal sheets
    under high plastic deformation by form and force closure without thermal support
    and auxiliary parts. Clinch connections are applicable to difficult-to-join hybrid
    material combinations, such as steel and aluminum. Therefore, this technology
    is interesting for the application of AISI 304 components, as this material is
    widely used as a highly formable sheet material. A characteristic feature of AISI
    304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can
    transform into a significantly stronger body-centered cubic (bcc) α’-martensite
    under plastic deformation. This work investigates the effect of heat treatment—a
    process that involves the formation of an oxidation layer on the sheet surface—on
    the forming process during joining and the resulting mechanical properties of
    clinch joints made from AISI 304. For this purpose, different joints made from
    non-heat treated and heat-treated sheets were examined using classical metallography
    and advanced SEM techniques, accompanied by further investigations, such as hardness
    and feritscope measurements. The shear tensile strength was determined, and the
    fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced
    surface roughness on the joint geometry and strength were observed.

  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.

  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: '<jats:p>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.</jats:p>'

  text: This article presents the application and evaluation of a cantilever with
    integrated sensing and actuation as part of an atomic force microscope (AFM) with
    an adjustable probe direction, which is integrated into a nano measuring machine
    (NMM-1). The AFM, which is operated in closed-loop intermittent contact mode,
    is based on two rotational axes that enable the adjustment of the probe direction
    to cover a complete hemisphere. The axes greatly enlarge the metrology frame of
    the measuring system by materials with a comparatively high coefficient of thermal
    expansion, which ultimately limits the achievable measurement uncertainty of the
    measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign
    of the rotational kinematics is mandatory. However, in this article, some preliminary
    investigations on the application of a self-sensing cantilever with an integrated
    micro heater for its stimulation will be presented. In previous investigations,
    a piezoelectric actuator has been applied to stimulate the cantilever. However,
    the removal of the piezoelectric actuator, which is enabled by the application
    of a cantilever with an integrated micro heater, promises an essential simplification
    of the sensor holder. Thus, in the future it might be possible to use materials
    with a low coefficient of thermal expansion, which are often difficult to machine
    and therefore only allow for rather simple geometries. Furthermore, because of
    the creepage of piezoelectric actuators, their removal from the metrology frame
    might lead to improved metrological characteristics. As will be shown, there are
    no significant differences between the two modes of actuation. Therefore, the
    redesigned rotational system will be based on the cantilever with integrated sensing
    and actuation.

  text: Predicting the durability of components subjected to mechanical load under
    environmental conditions leading to corrosion is one of the most challenging tasks
    in mechanical engineering. The demand for precise predictions increases with the
    desire of lightweight design in transportation due to environmental protection.
    Corrosion with its manifold of mechanisms often occurs together with the production
    of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the
    most feared damage mechanisms for metal constructions often leading to early and
    unexpected failure. Until now, predictions are mostly based on costly experiments.
    Hence, a rational predictive model based on the fundamentals of electrochemistry
    and damage mechanics has to be developed in order to reduce the costs. In this
    work, a first model approach based on classical continuum damage mechanics is
    presented to couple both, the damage induced by the mechanical stress and the
    hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent
    theory is applied to describe the mechanical damage due to fatigue. The electrochemical
    kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion
    equation to consider the impact of hydrogen embrittlement on the fatigue. The
    modeling of the mechanism of hydrogen embrittlement defines the progress of damage
    accumulation due to the electrochemistry. The durability results like the S-N
    diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue
    frequency or the stress ratio.

  text: Joining by forming operations presents powerful and complex joining techniques.
    Clinching is a well-known joining process for use in sheet metalworking. Currently,
    clinched joints are focusing on mechanically enhanced connections. Additionally,
    the demand for integrating electrical requirements to transmit electrical currents
    will be increased in the future. This integration is particularly important, for
    instance, in the e-mobility sector. It enables connecting battery cells with electrical
    joints of aluminum and copper. Systematic use of the process-specific advantages
    of this joining method opens up the possibility to find and create electrically
    optimized connections. The optimization for the transmission of electrical currents
    will be demonstrated for clinched joints by adapting the tool geometry and the
    clinched joint design. Based on a comparison of the electrical joint resistance,
    the limit use temperature is defined for the joining materials used based on the
    microstructural condition and the aging condition due to artificial aging. As
    a result of the investigations carried out, reliable current transmission at a
    constant conductor temperature of up to 120 °C can be achieved for clinched copper–copper
    joints. In the case of pure aluminum joints and mixed joints of aluminum and copper,
    long-term stable current transmission can be ensured up to a conductor temperature
    of 100 °C.

  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: Galvanic corrosion is a destructive process between dissimilar metals. The
    present paper presents a constructed numerical test case to simulate galvanic
    corrosion of two dissimilar metals. This test case is used to study the accuracy
    of different implementations to track the dissolving anode boundary. One technique
    is to numerically simulate a mesh displacement based on the prescribed displacement
    at the anode boundary. The second method is to adjust only the boundary elements.
    Re-meshing after a certain number of time steps is applied to both implementations.
    They produce similar results for an electrical and electrochemical field problem.
    This work shows that mesh smoothing does not result in higher accuracy when modeling
    a moving anode front. Adjusting only the boundary elements is sufficient when
    frequent re-meshing is used.

  text: As a joining-by-forming process, clinching and the use of functional elements
    enable low-energy joining of components through form, force, and, under certain
    conditions, material closure. In addition to the transmission of mechanical forces,
    these joining processes can be qualified for additional electrical contact within
    the scope of functional integration for electro-mobile applications. For this
    purpose, maximizing the force and material closure is necessary to ensure a long-term,
    stable transmission of electrical currents. To this end, the electrical properties
    of the joints were optimized. The investigations carried out show the long-term
    behavior under normal operating conditions and the short-circuit case.

  text: Clinching is a cost efficient method for joining components in series production.
    To assure the clinch point’s quality, the force displacement curve during clinching
    or the bottom thickness are monitored. The most significant geometrical characteristics
    of the clinch point, neck thickness and undercut, are usually tested destructively
    by microsectioning. However, micrograph preparation goes ahead with a resetting
    of elastic deformations and crack-closing after unloading. To generate a comprehensive
    knowledge of the clinch point’s inner geometry under load, in-situ computed tomography
    (CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive
    to the inner state of the clinch point, it could detect critical events like crack
    development during loading. If such events are indicated, the loading process
    is stopped and a stepped in-situ CT of the following crack and deformation development
    is performed. In this paper, the concept is applied to the process of clinching
    itself, providing a detailed three-dimensional insight in the development of the
    joining zone. A test set-up is used which allows a stepwise clinching of two aluminium
    sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system.
    In order to minimize X-ray absorption, a beryllium cylinder is used within the
    set-up frame and clinching tools are made from Si3N4. The actuator and sensor
    necessary for the TDA are integrated in the set-up. In regular process steps,
    the clinching process is interrupted in order to perform a TDA and a CT scan.
    In order to enhance the visibility of the interface, a thin tin layer is positioned
    between the sheets prior clinching. It is shown, that the test-set up allows a
    monitoring of the dynamic behaviour of the specimen during clinching while the
    CT scans visualize the inner geometry and material flow non-destructively.

  text: Given a steadily increasing demand on multi-material lightweight designs,
    fast and cost-efficient production technologies, such as the mechanical joining
    process clinching, are becoming more and more relevant for series production.
    Since the application of such joining techniques often base on the ability to
    reach similar or even better joint loading capacities compared to established
    joining processes (e.g., spot welding), few contributions investigated the systematic
    improvement of clinch joint characteristics. In this regard, the use of data-driven
    methods in combination with optimization algorithms showed already high potentials
    for the analysis of individual joints and the definition of optimal tool configurations.
    However, the often missing consideration of uncertainties, such as varying material
    properties, and the related calculation of their impact on clinch joint properties
    can lead to poor estimation results and thus to a decreased reliability of the
    entire joint connection. This can cause major challenges, especially for the design
    and dimensioning of safety-relevant components, such as in car bodies. Motivated
    by this, the presented contribution introduces a novel method for the robust estimation
    of clinch joint characteristics including uncertainties of varying and versatile
    process chains in mechanical joining. Therefore, the utilization of Gaussian process
    regression models is demonstrated and evaluated regarding the ability to achieve
    sufficient prediction qualities.

  text: Mechanical clinching is used to create lightweight hybrid structures. In order
    to estimate the service life of clinched components, its fatigue properties need
    to be known under different mechanical loading conditions. In addition to fatigue,
    corrosion is another factor that affects the fatigue life of clinched joints.
    In the literature, many corrosion and high-cycle fatigue damage models exist.
    However, little is known about how both phenomena interact in clinched joints.
    In this article, the influence of galvanic corrosion on clinched EN AW-6014/HCT590X + Z
    sheets on the fatigue life is investigated by means of numerical simulations and
    experimental results. An accurate prediction of the Wöhler lines of non-corroded
    and pre-corroded clinched specimens is shown.

  text: The conduction of structure-borne sound through joints causes energy dissipation.
    The sound reduction index describes this energy loss as a level decrease in the
    particle velocity across series-connected damping elements for which the superposition
    principle applies. This simple model can help to develop a testing method for
    joints based on this characteristic energy loss. In this paper, this model is
    experimentally evaluated for multiple in-series clinched aluminium sheets. Samples
    connected by several clinch points arranged in parallel are investigated experimentally,
    and the results are discussed.
