## Description

- description: A transient non-linear multiscale finite element heat flow-mechanical
    model to determine micro residual stresses (type III) and micro plastic strains
    in SAE-AISI 1524 gas tungsten arc welded joints is developed. To include anisotropy
    by preferred crystallographic orientation or texture, the global domain was decomposed
    into small subdomains based on the concept of representative volume elements (RVEs).
    A three-dimensional numerical procedure was developed by using the coupling DREAM.3D-ABAQUS.
    The macro scale temperature gradient information as prescribed driven (load) boundary
    conditions was used to calculate the meso-thermal cycles, and the meso-scale temperature
    gradient information was used to calculate the micro thermal cycles needed in
    the subsequent mechanical analysis. Anisotropy was included by randomly entering
    in each grain of the RVE specimen either the maximum Young’s modulus (Emax) in
    the stiffest direction <111>, or the minimum Young's modulus (Emin) in the least
    stiff direction <100>. Under this assumption, the averaging of the grain orientations
    over all grains in the textured polycrystal with greater number of grains occurred,
    and the strength was diluted by the spread of orientations present. Higher Mises
    stresses evolved in the sample with coarse grain size, which indicates that the
    strong dependence of residual micro stresses on grain size was reversed. The influence
    of the grain size on the response of the aggregates is clearly observed.
