中文摘要：

结构拓扑优化作为结构设计的重要组成部分,正变得越来越重要。目前国内外学者对结构拓扑优化的研究仍主要局限于材料的线性变形范围,但实际许多工程结构都会产生材料非线性响应,如设计在一定地震载荷下坏而不倒的房屋结构,此时要得到更加符合实际的拓扑构型,就需要考虑材料非线性进行结构拓扑优化设计。笔者对材料非纯属结构拓扑优化研究进行了综述,并提出了展望。

英文摘要：

Structure topology optimization,which is an important part of structure design,is becoming more and more important in recent years.At present,the research on structure topology optimization is mainly based on the theory of material linearity,in which the deformation of material is assumed linear.However,the nonlinear behavior of material occurs inevitably in practical engineering structures,such as house structure in earthquake area.It is demanded that the house can not be destroyed within a certain range of earthquke load.Therefore,the material nonlinearity must be taken into account in the research of structure topology optimization,so that the more practical topology structure can be obtained.In this paper,a review of researches on structure topology optimization with material nonlinearity was stated,and a brief expectation was presented.
