Experimental Investigations of Laser-induced Spall in Metallic Targets

1 Introduction The phenomena of laser-induced spall in metals have been reported in only a few papers, and most work was concentrated on aluminum and copper. Since the pulse intense laser can generate ultra-high strain rates more than 107 s-1, it becomes almost the unique means in laboratories for investigation of fracture behavior and mechanisms of materials under such extreme conditions. In this note, the preliminary results of spall experiments
