The effect of optical penetration on laser thermoelastically-generated ultrasound in non-metallic solids is studied theoretically on the basis of the thermoelastie equations. In one-dimensional model, on the assumptio...
Bascd on the non- linear thermoclastic theory, the temperature field and displacement field in a prestressed sample are obtaincd when a one-dimensional heat disturbance is applied to it. By using piezoelectric equatio...
On the basis of thermoelastic theory, a thermoelastic equivalent circuit model for laser-generated ultrasound has been proposed. With this model, laser-heated region is des cribed as a three-port electrical circuit wh...
