摘要
本文导出了弹性体总余能的变分极值条件,证明了它等价于弹性体变形几何方程和位移边界条件,从而表明了变形几何方程不是总余能变分的约束条件。
In this paper, it is shown that minimun complementary energy principle of elastic bodies is equal to the geometrical equation plus the displacement boundary condition of the body. So that geometrical equation deformation is met a constrainly condition.
