Polycrystalline model determining method for e.g. determining deformation on metal can, involves modifying number of representation grains or parameter of texture to adjust model based on comparison between theoretical and real behaviors

摘要

The method involves determining a theoretical behavior of a solid material by simulation using a polycrystalline model of a stress on the material, where the material is represented by representation grains regrouping orientation crystalline grains. The theoretical behavior is compared with a real behavior obtained from a mechanical test base. Number of representation grains or parameter of a texture utilized by the polycrystalline model is modified to adjust the polycrystalline model based on the comparison.
