  text: Most single-screw extruders used in the plastics processing industry are plasticizing
    extruders, designed to melt solid pellets or powders within the screw channel
    during processing. In many cases, the efficiency of the melting process acts as
    the primary throughput-limiting factor. If the material melts too late in the
    process, it may not be sufficiently mixed, resulting in substandard product quality.
    Accurate prediction of the melting process is therefore essential for efficient
    and cost-effective machine design. A practical method for engineers is the modeling
    of the melting process using mathematical–physical models that can be solved without
    complex numerical methods. These models enable rapid calculations while still
    providing sufficient predictive accuracy. This study revisits the modified Tadmor
    model by Potente, which describes the melting process and predicts the delay-zone
    length, extending from the hopper front edge to the point of melt pool formation.
    Based on extensive experimental investigations, this model is adapted by redefining
    the flow temperatures at the phase boundary and accounting for surface porosity
    at the beginning of the melting zone. Additionally, the effect of variable solid
    bed dynamics on model accuracy is examined. Significant model improvements were
    achieved by accounting for reduced heat flow into the solid bed due to the porous
    surface structure in the solid conveying zone, along with a new assumption for
    the flow temperature at the phase boundary between the solid bed and melt film.

  text: <jats:title>Abstract</jats:title><jats:p>Due to its excellent biocompatibility,
    pure iron is a very promising implant material, but often features corrosion rates
    that are too low. Using additive manufacturing and modified powders the microstructure
    and, thus, the material properties, e.g., the corrosion properties, can be tailored
    for specific applications. Within the scope of this study, pure iron powder was
    modified with different amounts of CeO<jats:sub>2</jats:sub> or Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    nanoparticles and subsequently processed by Electron Beam Powder Bed Fusion (PBF-EB/M).
    The corrosion-fatigue behavior of CeO<jats:sub>2</jats:sub> and Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    modified iron was investigated using rotation bending tests under the influence
    of simulated body fluid (m-SBF). While the modification using Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    showed reduced fatigue and corrosion-fatigue strengths, it could be demonstrated
    that the modification with CeO<jats:sub>2</jats:sub> is characterized by improved
    fatigue properties. The superior fatigue properties in air are attributed to the
    positive impact of dispersion strengthening. Additionally, an increased degradation
    rate compared to pure iron could be observed, eventually promoting an earlier
    failure of the specimens in the corrosion fatigue tests.</jats:p>

  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>In this study, we
    develop a novel multi-fidelity deep learning approach that transforms low-fidelity
    solution maps into high-fidelity ones by incorporating parametric space information
    into an autoencoder architecture. This method’s integration of parametric space
    information significantly reduces the amount of training data needed to effectively
    predict high-fidelity solutions from low-fidelity ones. In this study, we examine
    a two-dimensional steady-state heat transfer analysis within a heterogeneous materials
    microstructure. The heat conductivity coefficients for two different materials
    are condensed from a 101 <jats:inline-formula>\r\n              <jats:alternatives>\r\n
    \               <jats:tex-math>$$\\times $$</jats:tex-math>\r\n                <mml:math
    xmlns:mml=\"http://www.w3.org/1998/Math/MathML\">\r\n                  <mml:mo>×</mml:mo>\r\n
    \               </mml:math>\r\n              </jats:alternatives>\r\n            </jats:inline-formula> 101
    grid to smaller grids. We then solve the boundary value problem on the coarsest
    grid using a pre-trained physics-informed neural operator network known as Finite
    Operator Learning (FOL). The resulting low-fidelity solution is subsequently upscaled
    back to a 101 <jats:inline-formula>\r\n              <jats:alternatives>\r\n                <jats:tex-math>$$\\times
    $$</jats:tex-math>\r\n                <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\">\r\n

    \           </jats:inline-formula> 101 grid using a newly designed enhanced autoencoder.
    The novelty of the developed enhanced autoencoder lies in the concatenation of
    heat conductivity maps of different resolutions to the decoder segment in distinct
    steps. Hence the developed algorithm is named microstructure-embedded autoencoder
    (MEA). We compare the MEA outcomes with those from finite element methods, the
    standard U-Net, and an interpolation approach as an upscaling technique. Our analysis
    shows that MEA outperforms these methods in terms of computational efficiency
    and error on representative test cases. As a result, the MEA serves as a potential
    supplement to neural operator networks, effectively upscaling low-fidelity solutions
    to high-fidelity while preserving critical details often lost in traditional upscaling
    methods, such as sharp interfaces features lost in the context of interpolation
    approaches.</jats:p>"

  text: <jats:title>Abstract</jats:title><jats:p>The open-source parameter identification
    tool ADAPT (A diversely applicable parameter identification Tool) is integrated
    with a machine learning-based approach for start value prediction in order to
    calibrate a Gurson–Tvergaard–Needleman (GTN) and a Lemaitre damage model. As representative
    example case-hardened steel 16MnCrS5 is elaborated. An artificial neural network
    (ANN) is initially trained by using load–displacement curves derived from simulations
    of a boundary value problem—instead of using data generated for homogeneous states
    of deformation at material point or one-element level—with varying material parameter
    combinations. The ANN is then employed so as to predict sets of material parameters
    that already provide close solutions to the experiment. These predicted parameter
    sets serve as starting values for a subsequent multi-objective parameter identification
    by using ADAPT. ADAPT allows for the consideration of input data from multiple
    scales, including integral data such as load–displacement curves, full-field data
    such as displacement and strain fields, and high-resolution experimental void
    data at the micro-scale. The influence of each data set on prediction quality
    is analyzed. Using various types of input data introduces additional information,
    enhancing prediction accuracy. The validation is carried out with respect to experimental
    void measurements of forward rod extruded parts. The results demonstrate, by incorporating
    void measurements in the optimization process, that it is possible to improve
    the quantitative prediction of ductile damage in the sense of void area fractions
    by factor 28 in forward rod extrusion.</jats:p>
