摘要
随着各行业对钢材性能要求的提升,新一代先进高强钢成为了近年来研究的热点.先进高强钢大多具有双相或复相组织,为深入研究其变形行为,需对变形过程中应力应变配分进行分析.目前,结合实验手段与基于真实组织的晶体塑性有限元模拟是分析应力应变配分的有效方法之一.本文综述了目前常用的实验-晶体塑性有限元方法,及其应用于不同先进高强钢中的最新研究进展.在此基础上对其发展方向与研究前景进行了展望.
Due to the requirement for high performance steel,researchers focus on the new generation advanced high-strength steels.To analyze the deformation behavior of AHSS with dual phase or complex phase microstructure,the distribution of strain and stress has to be considered.Integrated experimental-real microstructure based crystal plasticity finite element method can provide convinced results in this field.This article reviews various experiments and crystal plasticity finite element method.The latest research status and progress are presented in this field.Finally,the development trend has been prospected.
