摘要
本文提出模拟岩石流变性持的弹-粘弹塑性模型,阐述了应用边界单元直接法解粘弹塑性问题的基本原理和全量初应力法解答问题的具体方法.计算结果表明,文中所采用的流变模型和边界单元计算程序是有效的.
In this paper,the theological model is presented,and the ba-sic principle of the viscoelastoplastic problem is worked out by the boundaryelement direct method,and the relevent formulations are derived.Several exam-ples show that the theological model and the corresponding boundary elementmethod presented in this paper are effective and reasonable.
