激光诱导冲击波的力学效应及其典型应用技术综述OA

Laser-induced shock wave is an intense transient mechanical effect generated by the interaction of a high-power,short-pulse laser with material,triggering plasma generation and rapid expansion.Its typical characteristics are the generation of extremely high peak pressures reaching GPa or even TPa levels within the material,accompanied by ultra-high strain rates of 107s-1.By precisely controlling this mechanical effect,a series of application technologies with engineering value have been developed.A systematic review of the generation mechanisms and propagation laws of laser-induced shock waves is presented,with a focus on elucidating the key technical principles and research progress in surface strengthening,precision forming,solid-state joining,controlled separation,and non-destructive testing.Future development directions for the deep integration of laser shock wave technology with artificial intelligence,digital twins,and green manufacturing are also outlined.The aim is to provide systematic theoretical support and technical references for in-depth mechanistic research,process parameter optimization,and the promotion of this technology in high-end manufacturing fields such as aerospace,energy equipment,and electronic information.
