Analytical model of the shape of the temporary gunshot cavity

Włodarczyk E., Maruszyński M.

Journal of Technical Physics

2004

Vol. 45, no 4

289-299

The analytical method, describing the shape of the temporary pulsating gunshot cavity, has been presented in this paper. A non-viscous incompressible liquid approximates the tissues of the living organism. The simple algebraic formula, determining the trajectory of the rigid projectile penetrating into incompressible liquid, has been derived. The shape of the temporary gunshot cavity is determined with the aid of envelope of the expanding bubbles family. The centers of the bubbles are placed along the projectile trajectory. The results of the theoretical analysis, presented in this paper, are compatible with the experimental data.
