Abstract

Abstract: Thermal Prophet-RVE (THP-RVE), a real microstructure-based mesomechanical modeling and simulation toolkit, was independently developed recently for particular application to property predictions for polycrystalline materials. In this paper, the basic framework, key features and the implementation technologies of THP-RVE were firstly introduced, then the deformation caused by martensite transformation in steel production and the mesomechanical behaviors under tensile loads of a ferrite/martensite dual-phase steel were simulated separately by using THP-RVE. The results show that the microstructural model constructed based on the actual material microstructure data can highly revivify the geometrical topological relationship among phase compositions and grains in the microstructure, and the mesomechanical model so established can be used to predict the deformation behavior and overall mechanical properties of polycrystalline materials under complex thermo-mechanical coupling.

Key words: Thermal Prophet-RVE, microstructure modeling, numerical simulation software, polycrystalline materials
