对来源于平面弹性问题的Hamilton算子的本征值问题进行了研究.在矩形域内含位移和应力的混合边界条件下,首先求解了相应算子的本征函数.接着,证明了本征函数系的完备性,这为施行分离变量法求解相应问题提供了可行性.最后,利用文中的辛本征展开定理获得了问题的一般解.
The eigenvalue problem of the Hamiltonian operator associated with the plane elasticity problems was investigated. First, the eigenfunctions of the operator with the mixed boundary conditions for the displacement and stress in the rectangular region was solved direct- ly. Then, the completeness of the eigenfunctions was proved, thereby demonstrating the feasi- bility of using separation of variables to solve the problems. Finally, the general solution was obtained by using the symplectic eigenftmction expansion theorem.
