Analysis of Microscopic Plastic Behaviors of metals considering slip deformation of crystals(I)

결정의 슬립을 고려한 금속의 미시적 소성변형거동 해석(I)

Finite element calculations are performed for crystalline solids subjected to plane strain tensile loading. Using Asaro's double slop model, shearband developments in single crystals are analyzed. The effect of various rate sensitivities and latent hardening parameters on microscopic plastic behavior was clarified. Moreover the deformation behavior of polycystals which have grain boundaries was compared to that of single crystals.
