【摘要】 本文介绍了作者们研制的大型边界元分析程序BEAP—II,该系统能解算二维、轴对称体及三维结构的应力分析与裂纹应力强度因子。数值求解引入子域与非对称矩阵的子城波前法,中心存储只需保留一到两个矩阵段,因而能解算大型工程问题。BEAP—II 程序具有统一的数据库、前后处理、求解器和单元库。文中给出了工程应用例的计算结果。更多还原

【Abstract】 In this paper,a large program system BEAP-Ⅱ of boundary elementanalysis developed by the authors is presented.This program can solve the stressanalysis problems of two and three dimensional continuum and exissymmetric bodyand the stress strength factor of crack.On numerical solution,due to having used thesubregion and the subregion frontal solution for unsymmetric matrices for thisprogram,only one or two matrix sections need to be reserved in internal storage.Therefore this program can solve large engineering problems.BEAP-Ⅱ has unifieddata base,pre and post processors,solver and element library.Also this paper givesthe calculated results of some example in applied engineering.更多还原
