Abstract

An analytical model for the pulsed laser generation of ultrasound in an adhesively bonded three-layered plate is presented. The model gives the time domain displacement of the plate as a function of laser characteristics and materials properties. Simulation of ultrasonic wave motion in three-layered plate is solved here with the finite element analysis. Detailed descriptions of ultrasonic waves are presented. The simulation allows a better understanding of the generation and propagation of laser-generated ultrasonic by creating a window of observation in the three-layered structure.
