Tóm tắt:
Simulate the laserinduced ablation in air and in water to compare the induced stress between the two ablation regimes First, the simulation is carried out to reconstruct the experimental images obtained by photoelasticity imaging technique for in-air and in-water ablation. Then, the Von Mises Stress is elucidated from simulation for each regime. The result confirms the stress enhancement effect of water layer and showed that the stress is increased by at least two orders of magnitude if the ablation is carried in water.
