边界元法在粘塑性分析中的应用

The Application of the Method of Boundary Element in Analysising Viscidity - plasticity

本文介绍了边界单元法在粘塑性分析中的应用,采用Perzyna近似方法模拟纯弹性解,用简单的欧拉单位步长过程得到了与时间相关的解,并且讨论了选取时间步长的准则。该方法也可用于求解蠕变问题。

The paper introduce the application of the method of Boundaty element in the problem of viscidity- plasticity.By the approximation of Perzyna to simulate the pure elastic resolution we can get the answer time - dependent with the simple eulor unit-step and discussing the criterion of the choice of time - step. This method can be used to solve the squirming problem.
