摘要: 从质量和动量守恒关系出发,导出了不可压缩刚塑性球壳在球面散心和聚心爆轰作用下的运动方程。应用本文结果计算球壳的加速运动与实验结果及动力有限元程序DYNA的数值摸拟结果吻合。Abstract: A method of calculating the deformation of a sphere as a result of divergent or convergent detonation of an explosive is presented. This method bases on the conservation of mass and momentum, and assumes the sphere material is incompressible and rigid plastic. The accelerated movement of a sphere calculated with this method is in good agreement with the experiment and the numerical result performed with the finite element hydrocode DYNA.
