摘要
本文应用Betti互等定理,推导出弹性体边界和体内受有限个集中荷载作用时的边界元法,弥补了常规边界元法在处理集中荷载方面的不足。算例结果表明本文方法是有效的。
It is difficult to analysis concentrated force by common BEM. In this paper, A new method is berived to solve the problem concerned concentrated force. The examples show that. the method is efficient. With high accuracy and less elements, the special BEM can reflect the results of concentrated loads efficiently.
