高次勾配結晶塑性理論の３次元問題への適用

抄録

To reproduce deformation behavior of metallic materials at the micro-meter scale, analysis based on a higher-order gradient crystal plasticity theory, which reflects behavior of geometrically necessary dislocations and takes size dependence into account, has been conducted in previous studies. However, for three-dimensional problems, analysis based on a formulation fully consistent with the complete mathematical structure of higher-order gradient crystal plasticity theory has not been performed. In this study, we adopted micropillar compression problem as an example of three-dimensional problem, and the analysis was based on a fully consistent formulation of higher-order gradient crystal plasticity theory.
