Stress wave propagation, laser-induce

Fig. 20 Simulation of the propagation of the laser-induced stress wave as a function of distance from the irradiation spot. A three-dimensional finite element analysis program has been employed. The simulation shows that the highest probability for delamination is at the interface just behind the irradiation spot. This prediction is verified in the irradiation of nonannealed polymer samples on Suprasil...
