摘要
研究了边界元——拉氏变换法在三维弹性动力学问题应用中的若干技术细节,如 Durbin 数值反演技巧、单元离散方案选择及频率对计算精度的影响等,获得了十分有益的结论.
Some details of the techniques in the 3-D elasto-dynamic problems
by applying Laplace transformed-boundary element method are studied in the
paper,Such as the technique of Durbin's numerical inversion,the discretiza-
tion of boundary element and the effect of frequency to computation accu-
racy.Some useful conclusions are obtained.
