Research progress in crystal plasticity deformation mechanisms and their numerical simulation methods

The application of crystal plasticity finite element numerical simulation has been studied, describing algorithms for crystal plasticity theory, crystal plasticity deformation mechanisms, and hardening mechanisms. The advantages of electron backscatter diffraction (EBSD) technology in crystallographic texture measurement and analysis have also been highlighted. By utilizing diffraction patterns, accurate information on crystal structure and orientation can be obtained, providing precise data input for crystal plasticity finite element numerical simulation. Consequently, existing crystal plasticity theories, parameter acquisition methods, and diffraction image analysis methods have been summarized. Currently, extensive verification has proven the effectiveness of this method in simulating metal plastic deformation mechanisms, and it has been widely used in the research of material plastic deformation mechanisms. This discussion is based on a systematic framework for crystal plasticity finite element numerical simulation research, aiming to comprehensively understand the progress of crystal plasticity finite element analysis in processing, and to offer new ideas for the design, optimization, and practical application of high-performance materials.
