研究刚塑性压缩问题的一种新方法

A New Method on solving the Rigid-Plastic Com pressing Problem

本文采用线性速降函数建立刚塑性问题的基本解,并由此导出求解刚塑性问题的增量型边界积分方程及边界单元法的公式。利用这些公式对刚塑性平面应变压缩问题进行了计算,计算结果与实测结果进行了比较,二者符合程度较好。

The fundamental solution for solving rigid plastic problem is established by using the linear fast descending function, from which the boundary integral equation and formulations of boundary element method are derived in the present paper. The rigid plastic plane strain compressing problem is solved by those formulations. The calculated results show a good agreement with experimental ones.
