摘要
提出一种供弹性空问结构系统进行数值计算的BEM—FEM耦合分析方法,适用于对称的和非对称的结构,可以承受分布的或集中的荷载作用。结合大直径圆筒结构算例的计算分析,证实这一方法在求解无限域或半无限域介质中弹性空间结构系统时,是一种很有效的方法。
A method of BEM-FEM coupled analysis for the numerical computation of elastic spatial structure is presented. It can be used to analyze both the symmetrical and non-symmetrical structures under distributed and concentrated load. Numerical examples and the analysis of a large-diameter cylinder show that the proposed method is quite efficient in solving elastic spatial structure problems.
