余虚功原理
1.
This paper applies Ritz and Galerkin method in elastic mechanics,deducts complementary virtual work principle with basic formula of elastic mechanics,and then gains minimal complementary energy principle to show that Ritz method and Galerkin method are equivalent,which illustrates that there are relative relationships between variational principle and weighted residual method.
将里茨法(Ritz)和伽辽金法(Galerkin)应用于弹性力学,由弹性力学基本方程推导出余虚功原理,进而求得最小余能原理,从而说明里茨法和伽辽金法是等价的,这也说明变分原理与加权残数法之间有亲缘关系。
