  text: <jats:p>In order to make rail transportation more attractive compared to motorized
    private transport, intelligent solutions are required across the entire mobility
    chain. Train stations, as places of connection and transfer, offer the greatest
    potential in this context. Thus, the deployment of autonomous service robots at
    train stations offers a wide range of possibilities for supporting passengers
    on their journeys by rail, for example, by providing information, accompanying
    them to the next link in the mobility chain, or transporting their luggage. Since
    such robots are battery-powered, one challenge is to carefully plan activities
    based on the remaining battery capacity. Therefore, the aim of this work is to
    predict battery usage and, in turn, battery state, in order to inform passengers,
    and to enable intelligent planning of its usage.In this work, realistic operational
    conditions of a service robot are systematically assessed through measurements
    on the service robot itself and through passenger surveys at a train station.
    The estimated operational conditions are experimentally replicated to simulate
    the heterogeneous use of the battery pack, while acquiring condition monitoring
    data throughout its use. The battery pack is modeled based on the single particle
    model, which can robustly predict the battery state by simulating its usage considering
    past operational conditions. The approach is validated using experimental data
    obtained from simulating realistic usage. On the one hand, additional battery
    packs are employed, and on the other hand, the load is varied. The advantage of
    this approach lies in the ability to account for future changes, such as higher
    loads than anticipated, to provide robust predictions.This enables the intelligent
    use of service robots, offering passengers an improved service experience at train
    stations.</jats:p>

  text: This study presents a numerical approach using a 3D finite element model to
    quantify the remaining clamp load of a plastic nut joint after a specific time.
    The viscoelastic relaxation of a thermoplastic nut, which is predominantly screwed
    on a welding stud, is described by a material card using Prony Series. Prony Series
    are derived from experimental dynamical mechanical analysis with different moisture
    and fiber contents of the thermoplastic. Since plastic nuts usually do not have
    preformed threads, the increased temperatures and resulting stresses from the
    thread-forming process are considered in the simulation. An FE model is created
    and verified by substrate stress relaxation tests. Experimental clamp load measurements
    with miniature compression load cells verify the clamp load prediction and show
    a good agreement. The developed model is used to analyze the clamp load distribution
    within the threads and reveals an almost even distribution within the threads.

  text: Die Transformation der bisher linearen Wirtschaft zu einer Kreislaufwirtschaft
    und einer möglichst emissionsneutralen Herstellung und Verwendung von Produkten
    bedarf einer ganzheitlichen Forschung und Entwicklung in allen Bereichen der Prozesskette.
    Die Fügetechnik gilt dabei als Enabler moderner Hybridstrukturen und ermöglicht
    die anforderungsgerechte Verbindung artverschiedener Werkstoffe mit unterschiedlichen
    technisch-wirtschaftlichen Eigenschaftsprofilen. Aktuelle Herausforderungen umfassen
    das qualitätsgesicherte Fügen bei einer zunehmenden Materialvielfalt aus Primär-
    und Sekundärwerkstoffen sowie das gezielte Entfügen von Leichtbaustrukturen in
    Instandsetzungs- oder Recyclingprozessen. Ein weiterer Entwicklungsschwerpunkt
    liegt auf der menschzentrierten Ausrichtung von Arbeitsprozessen. So können Arbeitskräfte
    durch eine ergonomische Produktions- und Fügeprozessplanung sowie die Entwicklung
    und Einbindung prozessbegleitender Mixed-Reality-Technologien gezielt entlastet
    und dem derzeit zu verzeichnenden Fachkräftemangel effektiv begegnet werden. Das
    vorliegende Whitepaper zeigt aktuelle Herausforderungen in der Fügetechnik auf,
    fasst relevante Erkenntnisse und Lösungsansätze aus Industrie und Forschung sowie
    dem Verbundforschungsvorhaben „Konzepte für die ressourceneffiziente und sichere
    Produktion von Leichtbaustrukturen“ (KORESIL) zusammen und leitet geeignete Handlungsempfehlungen
    für die Industrie ab. Diese sollen beteiligten Anwendern strategische Ansätze
    aufzeigen, um Prozesse ressourceneffizienter und nachhaltiger gestalten zu können.

  text: Powertrain concepts incorporating renewable energies are an essential element
    of the energy revolution and increasingly require efficient manufacturing processes
    for electronic systems. Particularly, the joining of structures to be thermally
    coupled, such as the battery modules and the thermal management system (TMS),
    poses new challenges in process design. Factors that limit the process include
    the increased density, viscosity, and abrasiveness of thermal pastes as well as
    the pressure sensitivity of battery modules. The research presented aims to systematically
    investigate the influences of joining parameters on flow behavior, the formation
    of air inclusions, and the occurring joining forces to understand and systematically
    optimize the joining process. Employing a test setup following the Closing-Hele-Shaw-Cell,
    the influence of specific process parameters on the joining process such as the
    joining speed, joining gap, application pattern, and temperature was investigated
    for a silicone- and a polyurethane-based thermally conductive paste. The results
    indicate a high dependency of both the ensuing joining forces and the flow behavior
    on the parameters investigated. These insights imply a potential systematic parameter
    optimization and the specific adaptation of the joining process to improve flow
    behavior and reduce compressive stresses. This can ensure lower component deformations
    and qualify the process for the employment of cell types with a higher power density,
    a reduced encapsulation, and lower stiffness while at the same time improving
    production rates.

  text: Im Rahmen des BMBF-Forschungsvorhabens KORESIL wurden entlang einer beispielgebenden
    Prozesskette für hybride Leichtbaustrukturen notwendige Forschungs- und Entwicklungsschwerpunkte
    ermittelt. Insbesondere die Steigerung der Ressourceneffizienz und die Unterstützung
    des Menschen im Kontext zukünftiger Arbeitsumfelder standen dabei im Mittelpunkt
    der Arbeiten. Hierauf aufbauend konnten Handlungsempfehlungen für Wirtschaft,
    Wissenschaft und Politik abgeleitet werden. Das Projekt KORESIL ist eingebettet
    in das Projektnetzwerk des Forschungs- und Technologiezentrums für ressourceneffiziente
    Leichtbaustrukturen – FOREL. Dieses Zentrum wurde im Jahr 2013 als BMBF-Leuchtturmprojekt
    eingerichtet und ist eine offene, unabhängige Plattform zur Entwicklung von Hightech-Leichtbausystemlösungen
    in Multi-Material-Design für die Mobilität der Zukunft. Ziel der Plattform ist
    die Unterstützung von Entwicklungsprojekten, die Vernetzung der Leichtbauforschung
    innerhalb Deutschlands und die Zusammenführung verschiedener Förderinitiativen.

  text: <jats:p> To reduce CO<jats:sub>2</jats:sub> emissions, the industry, particularly
    in the mobility sector, focuses on lightweight vehicles with multi-material structures.
    As thermal joining processes are reaching their limits, mechanical techniques
    such as self-piercing riveting are being used. One innovative solution is the
    versatile self-piercing riveting process (V-SPR), which combines different material
    combinations with a multi-range rivet.<jats:sup> 1 </jats:sup> The joining process
    is divided into the piercing process and the forming process of the rivet head
    to the respective sheet thickness. The rivet shaft requires sufficient strength
    to punch through the punch-sided sheet, and sufficient ductility of the rivet
    head is required to form onto the punch-sided sheet. To achieve a combination
    of these requirements, local inductive heat treatment strategies are used for
    the rivet. To ensure reproducible rivet hardening, a specialised device has been
    developed for precise rivet positioning in the induction coil and the subsequent
    quenching process. The heat treatment differs in terms of hardening times and
    temperatures. In addition, the heat treatment is combined with a subsequent tempering
    process. The study aims to determine the resulting hardness distributions and
    microstructures of the rivet and to investigate the influence of different heat
    treatment strategies on joint formation and load-bearing capacities. The results
    show that a graded hardening profile has a positive effect on the spreading behaviour
    of the rivet foot and the forming behaviour of the rivet head. Furthermore, the
    load-bearing behaviour of the joints is increased. </jats:p>

  text: "In Haushaltskältegeräten werden in den letzten Jahren immer häufiger Vakuumisolationspaneele
    (VIP) eingesetzt. Hiermit ist es unter anderem möglich, dass die Geräte in die
    Energieeffizienzklassen A bis C klassifiziert werden können. Ein VIP besteht vereinfacht
    aus einer Schutzfolie, die nahezu gasdicht ist und einem Füllmaterial, welches
    für die Formstabilität im Vakuum zuständig ist. Aufgrund von technischen Alterungsprozessen
    kommt es mit der Zeit zu einem Anstieg des Innendrucks im VIP, wodurch die Wärmeleitfähigkeit
    des VIP steigt. Je nach Füllmaterial erfolgt dieser Alterungsprozess unterschiedlich
    schnell. Im Extremfall kann so ein neues Haushalts-kältegerät der Energieeffizienzklasse
    A nach 1 bis 3 Jahren nur noch als Klasse D bis F eingestuft werden.\r\nInnerhalb
    eines Forschungsprojekts wurden Haushaltskältegeräte mit VIP thermografisch untersucht.
    Im Rahmen dieser Studienarbeit wurde ein Versuchsaufbau entwickelt, mit dem die
    zeitliche Veränderung von Wärmebrücken begutachtet werden kann und so Rückschlüsse
    auf den Effizienzverlust der Geräte möglich sind. Der Funkionsnachweises dieses
    Versuchsaufbaus wurden an einem Haushaltskältegerät mit künstlich gealterten Vakuumisolationspaneelen
    durchgeführt. Diese Arbeiten bieten zukünftig die Möglichkeiten Haushaltskältegeräten
    mit VIP bezüglich ihres Degenerationsverhaltens besser zu beurteilen.\r\n"

  text: '<jats:p>Today’s ultrasonic transducers find broad application in diverse
    technology branches and most often cannot be replaced by other actuators. They
    are typically based on lead-containing piezoelectric ceramics. These should be
    replaced for environmental and health issues by lead-free alternatives. Multiple
    material alternatives are already known, but there is a lack of information about
    their technological readiness level. To fill this gap, a small series of prestressed
    longitudinally vibrating transducers was set up with a standard PZT material and
    two lead-free variants within this study. The entire process for building the
    transducers is documented: characteristics of individual ring ceramics, burn-in
    results, and free vibration and characteristics under load are shown. The main
    result is that the investigated lead-free materials are ready to use within ultrasonic
    bolted Langevin transducers (BLTs) for medium-power applications, when the geometrical
    setup of the transducer is adopted. Since lead-free ceramics need higher voltages
    to achieve the same power level, the driving electronics or the mechanical setup
    must be altered specifically for each material. Lower self-heating of the lead-free
    materials might be attractive for heat-sensitive processes.</jats:p>'

  text: <jats:p>Abstract. The assessment of mechanically joined connections, such
    as clinched connections, is usually conducted destructively. Applicable non-destructive
    testing methods like computed tomography are time-consuming and costly, or, like
    electrical resistance measurement, provide only a limited amount of information.
    A fast, non-destructive evaluation of the joints condition shall be made possible
    by using transient dynamic analysis (TDA). It is based on the introduction of
    sound waves and the evaluation of the response behavior after passing through
    the structure. This study focuses the application of TDA to clinched shear connections
    to evaluate the performance of the tactile measuring setup. Twenty-one series
    were investigated, covering variations in joining task, manufacturing and defect.
    The evaluation was carried out using machine learning to determine for which series
    characteristic signals may be detected. It was shown that a classification of
    the investigated specimens is possible, whereby the classification accuracy depends
    on the examined variation. Furthermore, the accuracy was evaluated as a function
    of frequency and results were concluded to identify the limits of the used measuring
    setup.</jats:p>

  text: "Woven fibre-reinforced polymers are used in a variety of application, especially
    where a low mass to stiffness ratio is required. Of paramount importance for the
    tailored mechanical properties these composite materials exhibit is the type and
    geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic
    composites are fabricated as laminates and subsequently exposed to forming processes
    which alter the geometry of the fibres unit cell and thus the local mechanical
    properties of the material. An approach utilising broadband ultrasonic waves is
    proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe
    dispersive behaviour of woven fibre-reinforced sheets is described in accordance
    with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model
    for a description of these periodically structured waveguides, the smallest repeating
    unit of the wave is modelled with periodic boundary conditions. The resulting
    dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally
    displays a periodicity in the wavenumber regime, which correspond with the size
    of the unit cell. Experimental studies of the dispersive behaviour of acoustic
    waves in woven fibre-reinforced samples also show a periodicity in the wavenumber
    regime, enabling a measurement procedure of the unit cell geometry."

  text: '<jats:p>Abstract. Clinching is a conventional mechanical joining process
    used in Multi-Material Design in the automotive sector. To receive the desired
    geometrical characteristics in clinch joints, correct process design is required.
    To reduce the cost of finding fitting process parameters, numerical simulation
    of the joining process can be used to predict the geometrical characteristics,
    such as interlock, instead of an experimental approach. These numerical simulation
    models consume computational resources and time. In this paper machine learning
    is used to find correlations between features of the joining process and geometrical
    characteristics in the joint. This serves the purpose of predicting the joint’s
    target values more resource-efficiently. Modelling with machine learning requires
    a structured dataset with sufficient parameter variation. To create this data
    base the following procedure was used. For joining partners, a HC340LA steel alloy
    with 2 mm material thickness was used punch-sided and an EN AW 5182 aluminum alloy
    with 1.5 mm thickness was used die-sided. For this combination a suitable tool
    combination and punch distance was experimentally identified. A finite element
    model was created to reproduce the joining process. For the modelling of the material
    of both joining partners flow curves determined by Vallaster et al. were used
    [1]. The punch and die were recreated digitally by opto-electronic measurements
    and transformed into a mesh suitable for numerical simulation. The model was validated
    by comparing process values like the maximum force applied by the punch and geometrical
    values in the joints cross section. Additionally, a process window for suitable
    punch distances was experimentally determined. Afterwards a variation of 70 different
    process designs was conducted with variants inside and outside the process window.
    The results were used for training, testing and validating various machine learning
    models. All models competed against each other to find the must suited model to
    predict every geometric value. To ensure good model performances and prevent the
    model from overfitting, a tenfold cross validation was used for validating the
    models. Analysis of the results gives the following key findings: i) Good predictability
    is reached for the interlock and sheet thickness of the joint. ii) Prediction
    neck thickness showed low error values, but also low correlation. iii)The prediction
    of those key values for evaluating clinch joint characteristics by machine learning
    models positively impacts needed resources in comparison to numerical models.</jats:p>'
