A comparison between experimental and theoretical displacement fields for the tangential force problem (which is a model of the thermoelastic regime for laser generated ultrasound) at an aluminum interface is reported. The numerical predictions are based on a standard formulation of the transient generation of elastic waves along a line source. In the configuration of a purely elastic thin plate, the cylindrical elastic waves are then detected on the other side by a point-like receiver. The experimental works is carried out with a pulsed Nd:YAG laser for the generation and a laser interferometric probe for the detection of ultrasonic waves.
