摘要/Abstract

摘要： 本文在著名的线弹性结构静动力分析程序SAP5及其微机版本SAP5P^[1]中加入适当的人工边界处理,发展了一套用于模拟弹性波问题的通用程序。数值结果表明,该程序能比较好地模拟弹性波在均匀介质中的传播过程。

关键词: 弹性波, 人工边界, SAP5, SAP5P

Abstract: In this paper, an universial program for the simulation of elastic waves were developed by adding some treatment routines of artificial boundary conditions to the famous program of SAP5 and its micro-computer version SAP5P. The numerical results presented show that the program simulated the propagation of elastic waves in the uniformly elastic media quite well.

Key words: elastic wave, artificial boundary condition, SAP5, SAP5P
