板壳大变形弹─—塑性有限条分析

Large Deformation Elastic-plastic Analysis of Plate Structure by the Finite Strip Method

本文将结构分析的线弹性有限条法推广到大变形弹─—塑性板壳结构的分析；分析中考虑了几何和材料双重非线性，并开发了该分析法的Ｃ语言程序包。它与有限无法相比可大量节约计算机的内存和机时，并可望推广到材料的塑性成形分析过程。与解析法和有限元法相比，结果令人满意。

In this paper,we exteiid the linear elastic finite strip method to large deflection e-lastic-plastic analysis of plate strticture In this analysis,the geometry nonlinear and the ma -terial nonlinear are considered at the same time.Preparing with the finite element method,themethod can save much computer memory and computing time,The results are satisfactorycompared with the known results. This method can be exfended to the analysis of plasticforming processes.
