Abstract

Abstract

The high-speed photography was applied to observe the expanding fracture of 45 steel cylinder shells driven by detonation.The clear photos of expanding process of steel cylinder shells were obtained. The fracture strains of the expanding steel shells increase with the strain-rate, and decrease when the strain-rate arrived at a certain constant. The plasticity peak during dynamic fracture was experimentally observed. The strain-rate according to the peak of fracture strain is around 7.1104 s-1.
