The Finite Element Mesomechanics Simulation of Polycrystal Martensitic Transformation’s Plastic Strain

Abstract:

The plastic strain finite element mesomechanics simulation of polycrystal martensitic transformation bring up non-linear model of influence microscopic phase transition rate and stress. Further developement and application of Marc and on the base of microscopic chemical energy distribution, evenly. As the simulation showed: 1) Early into the plasticity than that of single crystal.2) Microplastic strain distribution is not uniform, microplastic strain maximum, minimum value ratio in different incremental step fluctuate greatly. 3) Meso martensitic transformation is not uniformly distributed, and uneven degree decreases with increment step. 4) The macro transformation rate simulation curves are exponential trend, and into the fully plastic state reached the point.
