Popis: | Generally, in the mesoscopic simulation of polycrystalline materials, correctly establishing polycrystalline models is the key to numerical simulate rolling process. Based on the principle of Voronoi diagram, using MATLAB and ABAQUS Python script interface, the rolling process of pure copper plates in the Voronoi polycrystalline meso-structure model was finite element simulated on ABAQUS platform in this paper. The result shows that because internal each grain has different orientations and interactions with each other, polycrystalline plates display an uneven deformation field in the rolling process and there is obvious stress mutation at grain boundary. These are consistent with the relevant experimental research results and reasonably explain deformation process of polycrystalline materials in theory. |
