Laser shock bulging is a high-strain-rate mechanical forming process in which the metal foil is plastically deformed under the effect of the shock wave induced by single or multiple laser pulses. In the process, fracture is one of the main forming defects and seriously affects the forming quality and production efficiency of bulged parts.
