摘要
多极边界元法已经成功地应用于大规模工程计算中.得到并且证明了基于三维弹性问题的多极边界元法核函数分解的定理(定理1),完善了多击边界元法的数学理论.
The Fast Muotipole Element Method (FM-BEM) has been applied to large scale engineering problems successfully. The Theorem of the fast multipole method (FMM) expansions of the kernels for FM-BEM based on 3D Elastic Problems are obtained and proved(Theorem 1), furthermore, the mathematical foundation of tile FM-BEM is completed.
