拜读了赵成刚、王进廷先生等的“流体饱和两相多孔介质动力反应分析的显式有限元法”(《岩土工程学报》2 0 0 1年第 2期 ,以下简称“原文”)一文 ,针对原文所提供算例中人工边界的设置问题 ,谈谈自己的看法 ,供大家参考。设置人工边界是为了用有限的计算区域模拟无限区域问题 , After reading the article entitled “Explicit Finite Element Method for Dynamic Response Analysis of Fluid-Saturated Two-Phase Porous Media” by Zhao Chenggang and Wang Jinting (Geotechnical Engineering Bulletin No. 2, 2001, hereinafter referred to as “original text”), The original text provided by the artificial boundary settings, to talk about their own views for your reference. Setting the artificial boundary is to simulate the infinite area problem with a limited calculation area,
