Abstract: In this paper, a numerical code is developed for the analysis of phased-array laser ultrasound. The signal enhancement of ultrasonic waves induced by a multi-beam laser source in phased array is simulated by using finite element method (FEM). The use of phased-array laser ultrasound for crack inspection with shadow method is investigated by simulation method.

Keywords: Laser ultrasonic, phased-array method, nondestructive testing, numerical simulation
