摘要

Thermal and mechanical responses of a cracked transparent conducing film to laser irradiation were investigated. A representative coin-shaped crack was modeled in the transparent conducing film and the case of vertical incidence of laser beam considered. Firstly, the multiple reflections, transmissions as well as absorptions are formulated in the quasi-multilayer media due to the effect of inner crack. Then, the temperature characteristics generated by the dissipated light energy are computed for the film of typical thermal boundary conditions. Finally, the thermal stress and stress intensity factors around the crack tip are particularly analyzed. The effects of the coin-shaped crack are discussed on the mull-physical responses of the film to laser irradiation.
