  • 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 directly.Then, the completeness of the eigenfunctions was proved, thereby demonstrating the feasibility of using separation of variables to solve the problems.Finally, the general solution was obtained by using the symplectic eigenfunction expansion theorem.
