## Description

- description: The yield-point phenomena in ferrite–pearlite duplex steels were investigated
    using multiscale computational simulations. In these multiscale simulations, the
    stress–strain relationship of the ferrite phase was characterized by an elastoplastic
    constitutive model considering the stress-drop behavior, and its material constants
    were determined by minimizing the residual error between a computational simulation
    and a tensile test experiment, where the yield-point phenomenon in a tensile test
    of ferrite steel was reproduced. Using the determined material response of the
    ferrite phase, finite element analyses of the ferrite–pearlite duplex microstructure
    were executed to scrutinize both the macroscopic material response and microscopic
    deformation mechanisms. Subsequently, finite element analyses of tensile tests,
    based on numerical results from microstructural analyses, were carried out to
    replicate the yield-point phenomena in ferrite–pearlite duplex steels. Consequently,
    the study characterized the strengthening effect of the pearlite constituent while
    considering microscopic heterogeneity and yield-point phenomena in the ferrite
    phase. The findings from the multiscale simulations underscored the necessity
    for a more accurate estimation of local mechanical properties in both the ferrite
    phase and pearlite constituent for quantitative simulations.
