摘要
基于作者发展的广义自洽有限元迭代平均化方法，利用增强相的平均应力集中因子对外荷载的敏感性，将光滑的金属基复合材料的弹塑性应力－应变曲线划分为多个特征变形区域，为完整地定义金属基复合材料的弹塑性变形提供了有效的手段．
The smooth elastoplastic stress-strain curves of metal matrixcomposites are divided into various characteristic deformation regions on thebasis of the sensitivity of the average stress concentration factor ofreinforcements to the variation of external load. The purpose of this method isto present effective means for the complete definition of the elastoplasticdeformation of metal matrix composites.
