Abstract: In this paper,a genernal model on sound reflection from a layered solid medium with rigid and slip interfaces that uses matrix method is proposed.Analytical expressions for reflection coefficients of both longitudinal and transverse waves from the layered solid medium with one or two slip interfaces are derived.Numerical results of sound reflection coefficients from some typical adhesive joints with slip interfaces,which may be useful for correct choice of technical parameters in ultrasonic evaluation of their interface features,are presented.
