Abstract
In this paper, the laser-induced Rayleigh wave and its interaction with sub-surface void in solid is numerically simulated by the finite element method. Typical calculation is executed for laser induced Rayleigh wave at the surface of solid without void and solid with circular void. The results provide necessary theoretical background for the nondestructive detection of laser ultrasonic.
