摘要
本文分析了爆炸环的高速膨胀和断裂过程,研究了它的破碎性与材料性能和断裂特性的关系,提出了爆炸环动态断裂的修正Kipp-Grady力学模型,导出了平均破片宽度的解析解。理论分析和实验结果吻合较好。本文研究结果可应用于有关工程破碎问题。
Rapidly expanding rings loaded by explosives are analyzed in this paper. Their fracture process and rupture characteristics as related to the behavior of materials are studied. A modified Kipp-Grady model for fracture energy is presented. Expressions are obtained for the nominal fragment size which are in good agreement with the experimental results.
