| Abstract: | The principles of virtual work and virtual complementary work with mixed variables, the principles of minimum potential energy and minimum complementary energy with mixed variables, the generalized principles of minimum potential energy and minimum complementary energy with mixed variables are established in this paper. Meanwhile,the bending of a rectangular plate with complicated boundary conditions is calculated by the principle of minimum potential energy with mixed variables. |
