摘　　要：分析约束层与激光相互作用时约束层碎裂的机理,用实验方法研究了约束层的厚度和柔性对激光冲击强化效果的影响。采用一定厚度及刚性的约束层,既能有效利用激光能量,又能获得较好的冲击强化效果。The interaction between the laser and overlay and the mechanism of overlay fracture under the action of laser - induced waves are analyzed. The effects of overlay thickness and mechanics properties on laser -induced shock waves are studied with a experimental method. The experimental results show that an appropriate overlay thickness and rigidity can not only use laser energy effectively but also provide optimal peak pressure of shock waves.
