Propagation of P wave (longitudinal wave) in layered half space is considered. Reflection and transmission coefficients at an imperfectly bonded interface are analyzed. The bonding strength at the interface is assumed as Joint Coefficient Dx and Dy, which represent tangential and normal direction joints of the jointed plane, respectively. The energy of reflected and transmitted wave is very sensitive, and resonance of the plate occurs for short wave lengths. It is more remarkable for small incident angles. When the bonding strength is strong, reflection and transmission coefficients show very complex variations. The relation between the two coefficients and bonding strength is also discussed.
