开口角隅应力集中的重复子域边界元法

Boundary Element Duplicated Sub domain Method for the Analyses of Open Corner Stress Concentration

针对具有重复结构的开口角隅应力集中问题建立了重复子域边界元法及有限元子结构与边界元耦合求解的基本列式。

This paper deduced the basic formulae of the 2 D boundary element duplicated sub domain method and formulae of the coupling method of 2 D boundary element with finite element sub structure, taking account of peculiarity of duplicated open corner structure. The numerical results show that computer program developed is correct.
