摘要
结构体的边界条件未能充分给出的情况下，用常规边界元法很难作出正确的结构分析。本文利用边界元法与非线性优化技术相结合，根据弹性体内或边界上的位移、应力等附加信息，建立了结构体面力重构的边界元逆分析法的基本模型，算例证明了该理论的有效性。
It is very difficulty to obtain the structural analysis correctly by the conventional boundary element method, when the boundary conditions is not given enough. Additional information such as displacements or stresses is provided at several internal or boundary points in the structure, combined with stochastic boundary element method and optimization technique, the basic model of the structural traction reconstruction by inverse analysis of boundary element method is presented in this paper. Numerical example is given to demonstrate the usefulness of the protested theory.
