Abstract

The interaction of ultrasonic waves with cracks is analyzed numerically in this paper. The nonlinear effect due to the asymmetric stiffness called contact acoustic nonlinearity (CAN) is focused. Longitudinal wave and Raleigh wave are excited separately to investigate their nonlinear interaction with cracks. Numerical results demonstrate that super-harmonics and sub-harmonics can be generated, and frequency of Rayleigh wave only in certain range can excite the harmonics when has some relations with depth of crack.
