摘要
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 10<sup>7</sup> s<sup>-1</sup>, 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
