摘要/Abstract

摘要： Thermal Prophet-RVE是最近自主开发的一款基于实际微观组织数据的多晶材料细观力学模拟软件。本文着重对其软件架构、基本功能及技术特点进行介绍,并模拟了铁素体/马氏体双相钢生产过程马氏体相变引起的变形和双相组织在拉伸载荷作用下的细观力学行为。结果表明,基于材料实际微观组织数据构建的微结构模型能够高度还原组织相组成以及晶粒之间的几何拓扑关系,由此建立的细观力学模型能够对多晶材料在复杂热力耦合作用下的变形行为以及整体力学性能进行可靠预测。

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
