摘要
拉压不同模量弹性体具有材料非线性特征,不同模量本构关系受到材料本身及结构各点的应力、应变状态等因素的综合影响.总结了近年来对不同模量本构关系的研究工作,阐述了多种形式的不同模量弹性问题有限元求解方法的改进,简述了拉压不同模量问题解析法取得的研究成果,并介绍了不同模量理论中尚待解决的问题.
Elastic bodies having different modules in tension and compression exhibit nonlinear behaviors. The constitutive equations of an elastic body with different modules depend on the material itself, and also on the stress and strain state of each point in the body. Recent achievements of research on the constitutive equations are presented. Also discussed are the improvements in the finite element method (FEM) employed to solve different module problems. Analytical methods of the elastic body with different modules are introduced. Problems to be solved net are outlined.
