| Abstract: | By using complete soft recovery technique, the deformation and macroscopical spalling characteristics of steel 20 tube under sliding inward explosion were investigated. Experiments were carried out with different kinds of solid high explosives (HE), with several HE thicknesses, and under different outer shell conditions. The quantitative result of critical thickness of HE for steel tube’s spalling was obtained, the influence of load intensity, HE thickness and outer shell on steel tube’s spalling were also analyzed. |
