【摘要】 近几年来，出于分析铸件中常出现的热裂、变形等问题的需要，凝固过程应力场、应变场数值模拟技术的研究日益受到重视，铸造过程温度场、应力场数值模拟技术的研究是铸造工程领域的前沿课题。本文介绍这一领域的研究进展情况，分析了存在的问题及发展方向。更多还原

【Abstract】 In the past few years,in the needfor analysing those problems such as thermalcrack,out of shepe,etc,which are often seem incast parts,researching work in numerical simulaation technology of stress-strain field during solidification,which is a forward problem in the area ofcast engineering,has attracted more and more attention. This thesis introduces progress in thisarea,and analyses existing problems and the direction of its development meanwhile.更多还原
