Computer Simulation Of Laser-Generated Elastic Waves In Solid
Source abstract
Abstract
Abstract A two-dimensional numerical simulation of elastic waves generated by pulsed-laser irradiation is carried out in order 10 understand the generation and propagation behavior of the waves in a solid. A computer simulation method using nodal equations is employed to visualize the elastic waves in asolid. Thermal stresses and vaporizing pressures induced by laser irradiation are included in the simulation model, respectively as horizontal and vertical external stresses at solid surface. Additional effects such as thermal conduction or depth of laser-heated zone, are not considered. The generation and propagation of longitudinal, shear. and surface waves are simulated, and variations of the wave form relating to thermoelastic effect, vaporization pressure and laser beam profile are shown.
