K-0335 Computational Simulation of Deformation Behavior of TRIP steel Based on Homogenization Method

Abstract

The transformation-induced plasticity (TRIP) steel possesses such favorable mechanical properties as tenacity and strength due to strain-induced martensite transformation. This excellent mechanical properties of TRIP steel depend on inhomogenious morphology of martensite in microscopic region. However, to evaluate the effect of microscopic morphology of martensite on its mechanical properties, it is difficult to express microscopically its heterogeneous deformation behavior by a conventional FEM. Here, the computational simulation of deformation behavior of TRIP steel is performed by recently developed homogenization method.
