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.

Martensite Volume Fraction

Stress-strain responses of type SUS304 stainless steel at large strain under uniaxial tension and cyclic loading were investigated with special reference to plastic strain induced martensitic transformation. From the experiment it was found that the martensitic transformation plays an important role for the workhardening of the material at large strain, and a new finding from the cyclic experiment is that the stagnation of martensitic transformation appears at an early stage of reverse deformation. The evolutions of martensite volume fraction during monotonic and cyclic deformations were calculated by Stringfellow model, and it was found that the model is accurate enough for predicting the martensite volume fraction vs. plastic strain curve under monotonic loading case. On the other hand, it significantly overestimates the evolution of martensite volume fraction in a cyclic deformation.
