摘要: 利用完整回收技术,获得了20钢圆管在不同固体装药厚度、装药类型以及外壳条件的滑移内爆加载下形变和层裂的特征和规律，得到了钢圆管层裂的相对临界装药厚度等初步结果，分析了装药类型、装药厚度、外壳对钢圆管层裂的影响。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 tubes spalling was obtained, the influence of load intensity, HE thickness and outer shell on steel tubes spalling were also analyzed.
