Abstract

The objective of the paper is to analyze, using computer simulation, the thermoelastic generation of ultrasonic perturbations in semitransparent solids when the heat source is a laser radiation. The algorithm, the numerical analysis relies on, will takes into account three main physical phenomena: the absorption of electromagnetic energy in substance with heat generation; thermal diffusion and elastodynamic wave generation by thermoelastic expansion.
