摘要
阐明和应用了有限元法的基本原理,建立了构造应力场分析的数学力学模型,并提出了两种适合计算机运算的构造应力场及演方法(力法反演和位移法反演)。据两种反演方法的原理和应用,介绍两种构造应力场计算程序及使用方法。
Based on the basic principle of finite element method, mathmechanics model ofstructure stress field analysis is constructed and two structure stressfield inverse meth-ods are given (shift method and stress method), which are suitable to computer calcu-lating. According to the two inverse methods, we have made up two common calculat-ing programs which can inverse the structure stress field.
