Circumferential strains from the numerical calculations are in good agreement with the plastic strains from recovered fragments. Additionally, considerable insights into the dynamics of the explosive launch process are obtained by comparing spall failure and nucleation and growth of ductile voids in the recovered fragments against the numerical simulations.

To investigate the initial velocities from a cylindrical cased charge detonated at the point on the axis, the flash X-ray radiography system was used to test the velocities of the end caps, and the influence of the axial position of the detonation point was further studied by simulation. The experimental results show that when the thickness of the end cap is equal to that of the casing and the ratio of length to diameter is 3, the velocity of the front end cap is 0.53 times that of the rear end cap. The simulation results show that the initial velocities and energy distribution are affected by the height from the detonation point to the end, and the conversion efficiency of the explosive energy can be increased by adjusting the detonation height and the charge length.
