板壳塑性极限分析的权余法

A Plastic Limit Analysis of Plate and Shell with Mwr

本文将加权余量法用于板壳的塑性极限分析,采用了最小二乘法、子域法、矩量法,以二次或三次多项式作为试函数,解决了某些矩形薄板、圆柱壳及圆锥壳的极限载荷问题.

This paper discusses a plastic limit analysis of plate and shell by means of the Method of Weighted Residuals (Least Squares Method, Subdomain Method, and Method of Moment).The limit loads of some rectangle thin plate, cylindrical shell and conical shell are solved with quadric or cubic polynomical as trial functions in the paper.
