多孔直杆扭转问题的边界元法

讨论了用边界元法解多孔直杆弹性扭转问题，证明了求具有等值面边界条件的非局部边值问题的解与求对应的边界积分方程的解是等价的，并将计算中出现的区域积分全部化为边界积分，从而减少了所需准备的初始数据和计算时间。

Boundary Element Methods for Elastic Torsion of Multihole Bars

The author discusses the boundary element method (BEM )for the problem of elastic torsion of the multihole bars, and proves that finding the solution of the nonlocal boundary value problem is equivalent of finding the solution of the corresponding boundary integral equation. The integrals over the region are transformed into the ones along its boundaries so that the data to be prepared and the time in computation are reduced.
