Laser shock hardening may change the structure and properties through forming shock wave and causing damage in the surface layer of metal.

We find that when the collapsing bubble approaches its minimum radius, a high pressure layer just outside the bubble is generated which gradually moves outward and subsequently forms a shock wave.

计算还发现，当气泡接近它的最小半径处，气泡外围形成很薄的高压区，这个高压区域随后向外传播，这就形成冲击波。
