Original Abstract

A method for ultrasonic nondestructive testing of nonlinear elastic materials (structural elements) is elaborated. Simultaneous propagation of two longitudinal waves, their reflection and interaction data are utilized. Convenient choice of the wave frequency makes it possible to analyze the data recorded on the boundaries of the specimen in terms of wave harmonic. A detailed analysis of the harmonics evolution and interaction is presented. It is shown that amplitudes of the harmonics and phase shifts are sensitive to material properties.
