A THEORETICAL ANALYSIS FOR INITIAL FRAGMENT VELOCITY AND PEAK OVERPRESSURE OF A BLAST FRAGMENTATION DEVICE

摘要

In the present paper, the peak overpressure and initial fragment velocity were derived under some theoretical assumptions for a blast fragmentation device, which consists of a fore hemi-spherical shell, a cylindrical body shell and an aft end. The blast fragmentation device with non-uniform wall thickness was especially concerned in this paper. The theoretical analysis was compared with some test results, and a good accordance was achieved.
