  text: <jats:p>In this study, the design, additive manufacturing and experimental
    as well as simulation investigation of mechanical and thermal properties of cellular
    solids are addressed. For this, two cellular solids having nested and non-nested
    structures are designed and additively manufactured via laser powder bed fusion.
    The primary objective is to design cellular solids which absorb a significant
    amount of energy upon impact loading without transmitting a high amount of stress
    into the cellular solids. Therefore, compression testing of the two cellular solids
    is performed. The nested and non-nested cellular solids show similar energy absorption
    properties; however, the nested cellular solid transmits a lower amount of stress
    in the cellular structure compared to the non-nested cellular solid. The experimentally
    measured strain (by DIC) in the interior region of the nested cellular solid is
    lower despite a higher value of externally imposed compressive strain. The second
    objective of this study is to determine the thermal insulation properties of cellular
    solids. For measuring the thermal insulation properties, the samples are placed
    on a hot plate; and the surface temperature distribution is measured by an infrared
    camera. The thermal insulating performance of both cellular types is sufficient
    for temperatures exceeding 100 °C. However, the thermal insulating performance
    of a non-nested cellular solid is slightly better than that of the nested cellular
    solid. Additional thermal simulations predict a relatively higher temperature
    distribution on the cellular solid surfaces compared to experimental results.
    The simulated residual stress shows a similar distribution for both types, but
    the magnitude of residual stress is different for the cellular solids upon cooling
    from different temperatures of the hot plate.</jats:p>

  text: <jats:p>The additive manufacturing (AM) of innovative lattice structures with
    unique mechanical properties has received widespread attention due to the capability
    of AM processes to fabricate freeform and intricate structures. The most common
    way to characterize the additively manufactured lattice structures is via the
    uniaxial compression test. However, although there are many applications for which
    lattice structures are designed for bending (e.g., sandwich panels cores and some
    medical implants), limited attention has been paid toward investigating the flexural
    behavior of metallic AM lattice structures with tunable internal architectures.
    The purpose of this study was to experimentally investigate the flexural behavior
    of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio
    (PR). Four configurations of lattice structure beams with positive, negative,
    hybrid PR, and a novel hybrid PR with graded density were manufactured via the
    laser powder bed fusion (LPBF) AM process and tested under four-point bending.
    The manufacturability, microstructure, micro-hardness, and flexural properties
    of the lattices were evaluated. During the bending tests, different failure mechanisms
    were observed, which were highly dependent on the type of lattice geometry. The
    best response in terms of absorbed energy was obtained for the functionally graded
    hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed
    a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the
    positive PR (PPR) structure. This highlights the great potential for FGHPR lattices
    to be used in protective devices, load-bearing medical implants, and energy-absorbing
    applications.</jats:p>

  text: In this study, an innovative friction model is used to improve the quality
    of clinching process simulations. Consequently, the future over dimensioning can
    be reduced. Furthermore, the improved prediction quality of the joining process
    simulation leads to an improvement in the simulation of load-bearing capacity
    as well. In this way, the entire sampling process can be performed virtually without
    any experimental investigations. This will contribute to the advancement of lightweight
    construction in the automotive industry. In this work, the frictional behavior
    is studied in dependence on the local joining process parameters. As a reference
    for the numerical investigations, clinch joints by means of a die with fixed geometry
    are joined. Additionally, a hardness mapping is performed on the microsection
    of the clinch joints. It shows the local strain hardening, which correlates with
    the forming degree in the simulation. Based on the occurring contacts and the
    local joining process parameters in the joining process simulation, the test matrix
    for the experimental friction tests is defined. The friction tests are carried
    out on a compression-torsion-tribometer. This type of tribometer is able to apply
    high interface pressures above the initial yield stress due to the specimen encapsulation.
    Besides, the pure joining part contact, the contact between the joining part and
    joining tool can be tested as well. The experimental test setup offers the possibility
    to evaluate the influences of temperature, relative velocity, interface pressure,
    and frictional stroke independently. Based on the results of the experimental
    friction tests, a friction model is created. The resulting friction model is integrated
    into the numerical joining process simulation via a subroutine. To validate the
    quality of the new friction modeling, the results of simulations are compared
    with the experiments in terms of load-stroke diagrams, joint geometry, and hardness
    mappings on the microsection. </jats:p>

  text: <jats:p> Clinching as a mechanical joining process has become established
    in many areas of car body. In order to predict relevant properties of clinched
    joints and to ensure the reliability of the process, it is numerically simulated
    during the product development process. The prediction accuracy of the simulated
    process depends on the implemented friction model. Therefore, a new method for
    determining friction coefficients in sheet metal materials was developed and tested.
    The aim of this study is the numerical investigation of this experimental method
    by means of FE simulation. The experimental setup is modelled in a 3D numerical
    simulation taking into account the process parameters varying in the experiment,
    such as geometric properties, contact pressure and contact velocity. Furthermore,
    the contact description of the model is calibrated via the experimentally determined
    friction coefficients according to clinch-relevant parameter space. It is shown
    that the assumptions made in the determination of the experimental data in preliminary
    work are valid. In addition, it is investigated to what extent the standard Coulomb
    friction model in the FEM can reproduce the results of the experimental method.

  text: <jats:p>The production of complex multi-functional, high-strength parts is
    becoming increasingly important in the industry. Especially with small batch size,
    the incremental flow forming processes can be advantageous. The production of
    parts with complex geometry and locally graded material properties currently depicts
    a great challenge in the flow forming process. At this point, the usage of closed-loop
    control for the shape and properties could be a feasible new solution. The overall
    aim in this project is to establish an intelligent closed-loop control system
    for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces
    in a flow forming process. To reach this goal, a novel sensor concept for online
    measurements of the wall thickness reduction and the martensite content during
    forming process is proposed. It includes the setup of a modified flow forming
    machine and the integration of the sensor system in the machine control. Additionally,
    a simulation model for the flow forming process is presented which describes the
    forming process with regard to the plastic workpiece deformation, the induced
    α’-martensite fraction, and the sensor behavior. This model was used for designing
    a closed-loop process control of the wall thickness reduction that was subsequently
    realized at the real plant including online measured feedback from the sensor
    system.</jats:p>

  text: <jats:p>The further development of in-mold-assembly (IMA) technologies for
    structural hybrid components is of great importance for increasing the economic
    efficiency and thus the application potential. This paper presents an innovative
    IMA process concept for the manufacturing of bending loaded hybrid components
    consisting of two outer metal belts and an inner core structure made of glass
    mat reinforced thermoplastic (GMT). In this process, the core structure, which
    is provided with stiffening ribs and functional elements, is formed and joined
    to two metal belts in one single step. For experimental validation of the concept,
    the development of a prototypic molding tool and the manufacturing of hybrid beams
    including process parameters are described. Three-point bending tests and optical
    measurement technologies are used to characterize the failure behavior and mechanical
    properties of the produced hybrid beams. It was found that the innovative IMA
    process enables the manufacturing of hybrid components with high energy absorption
    and low weight in one step. The mass-specific energy absorption is increased by
    693 % compared to pure GMT beams.</jats:p>

  text: <jats:p>Requirement changes and cascading effects of change propagation are
    major sources of inefficiencies in product development and increase the risk of
    project failure. Proactive change management of requirement changes yields the
    potential to handle such changes efficiently. A systematic approach is required
    for proactive change management to assess and reduce the risk of a requirement
    change with appropriate effort in industrial application. Within the paper at
    hand, a novel method for Proactive Management of Requirement Changes (ProMaRC)
    is presented. It is developed in close collaboration with industry experts and
    evaluated based on workshops, pilot users’ feedback, three industrial case studies
    from the automotive industry and five development projects from research. To limit
    the application effort, an automated approach for dependency analysis based on
    the machine learning technique BERT and semi-automated assessment of change likelihood
    and impact using a modified PageRank algorithm is developed. Applying the method,
    the risks of requirement changes are assessed systematically and reduced by means
    of proactive change measures. Evaluation shows high performance of dependency
    analysis and confirms the applicability and usefulness of the method. This contribution
    opens up the research space of proactive risk management for requirement changes
    which is currently almost unexploited. It enables more efficient product development.</jats:p>

  text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
    two or more helical phase profiles of optical vortex beams. Recently, grafted
    perfect vortex beams (GPVBs) have attracted much attention due to their unique
    optical properties and potential applications. However, the current method to
    generate and manipulate GPVBs requires a complex and bulky optical system, hindering
    further investigation and limiting its practical applications. Here, a compact
    metasurface approach for generating and manipulating GPVBs in multiple channels
    is proposed and demonstrated, which eliminates the need for such a complex optical
    setup. A single metasurface is utilized to realize various superpositions of GPVBs
    with different combinations of topological charges in four channels, leading to
    asymmetric singularity distributions. The positions of singularities in the superimposed
    beam can be further modulated by introducing an initial phase difference in the
    metasurface design. The work demonstrates a compact metasurface platform that
    performs a sophisticated optical task that is very challenging with conventional
    optics, opening opportunities for the investigation and applications of GPVBs
    in a wide range of emerging application areas, such as singular optics and quantum
    science.

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

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>We performed
    a virtual materials screening to identify promising topological materials for
    photocatalytic water splitting under visible light irradiation. Topological compounds
    were screened based on band gap, band edge energy, and thermodynamics stability
    criteria. In addition, topological types for our final candidates were computed
    based on electronic structures calculated usingthe hybrid density functional theory
    including exact Hartree–Fock exchange. Our final list contains materials which
    have band gaps between 1.0 and 2.7 eV in addition to band edge energies suitable
    for water oxidation and reduction. However, the topological types of these compounds
    calculated with the hybrid functional differ from those reported previously. To
    that end, we discuss the importance of computational methods for the calculation
    of atomic and electronic structures in materials screening processes.</jats:p>"
