Advances in laser ultrasonics have opened new possibilities in medical applications, such as the characterization of skin properties. This paper describes the development of a multilayered finite element model ( FEM) using ANSYS to simulate the propagation of laser generated thermoelastic surface acoustic waves ( SAWs) through skin and to generate signals one would expect to observe without causing thermal damage to skin. A transient thermal analysis is developed to simulate the thermal effect of the laser source penetrating into the skin. The results from the thermal analysis are subsequently applied as a load to the structural analysis where the out- of- plane displacement responses are analysed in models with varying dermis layer thickness.
