Dynamic thermal shock in a layered cylinder with initial interface pressure

An analytical method is developed to determine the transient response of dynamic thermostress in a two_layered cylinder with initial interface pressure. At first, the initial interface pressure in a two_layered cylinder caused by a heat_assembling method is considered as the initial condition of a thermal elastodynamic equilibrium equation. Thus, a thermal elastodynamic solution for a separate hollow cylinder with the initial stress field is found out by means of a series of simply mathematical transform. By making use of the boundary conditions and continuity conditions of a layered cylinders, the solution for the thermal shock exerting an influence on the initial interface pressure in a two_layered cylinder is also discussed.
