Abstract
The model of ultrasonic propagation through contact interface was established by Hertz contact theory. From the Hertz contact theory, it is found that higher order harmonic wave and waveform distortion occur when the ultrasonic wave propagate through a contact interface between two isotropic solids pressed together. The experiment results show at contact interface pressure is less than 6 kPa, the nonlinear coefficient of the interface layer decreases. When contact interface pressure is in the range of 6 kPa to 10 kPa, higher harmonic wave and nonlinear coefficient is minimum l. When contact interface pressure is more than 10 kPa, the nonlinear coefficient increases as increasing of the interface pressure.
