3次元時間域異方性動弾性問題における高速多重極境界積分方程式法について

抄録

This paper discusses a fast multipole method for three dimensional anisotropic elastodynamics in time domain. A PWTD (plane wave time domain) approach is presented. The proposed approach is verified via a simple numerical example. The accuracy of the approach is shown to be satisfactory for engineering purposes, although its efficiency still needs to be improved.
