摘要：

This paper presents the solutions of stress at crack tip in singularity point domain in system of Hamilton with separation of variables and eigenfunction expansion. A new singularity point analytical element is built to analyze the crack. Two numerical examples are given to demonstrate the efficiency of computations in Hamiltonian system and the symplectic mathematics.
