演算子積分時間領域境界要素法を用いた飽和多孔質弾性体における大規模波動散乱解析
This paper presents a convolution quadrature time-domain boundary element method for a fluid-saturated porous medium. Large scale wave analyses for a fluid-saturated porous media using the conventional time-domain boundary element method (BEM) are not so popular for the following reasons: 1) No time-domain fundamental solutions are known for the problem, 2)The conventional time-domain BEM sometimes causes numerical instability, and 3) needs much computational time and memory. The formulation
