摘要
本文以二维半无限空间内压缩线源激发的P-SV波为对象,讨论了求解具有间断系数的二维弹性波方程组初边值问题的几种分步方法。震源的贡献是以一个边界条件给出的。为了检验本方法的功能,我们给出了两个计算实例。
Some methods of fractional steps for solving initial-boundary problems of two dimensional elastic wave equations which describe the P-SV wave propagation generated by linear compressional source in the 2-D hemi-indefinite space with discontinuous coefficients are discussed. A boundary condition is provided by the contribution of source. For examining the efficiency of these methods, two calculation examples are given.
