边界单元法中几个问题的处理

TREATMENT OF SOME PROBLEMS OF BOUNDARY ELEMENT METHOD

本文针对边界单元法中面力不连续问题、奇异积分问题、网格自动生成技术等,给出相应的处理方法.该方法简便、精度高、准备数据少,从而有效地利用高次单元解决了实际问题.

This paper presents effective approaches to the subjects of discontinuous surface traction, singular integration and technique of automatically dividing meshes. The methods are simple, of high accuracy and of less preperation of data. The prectical problems are effectively solved by higher-order elements.
