Abstract:

This report presents a general mathematical model of gelatin penetration which accounts for the effects of impact velocity, density, mass, and presented area of projectiles of several shapes spheres, cylinders, cubes, and irregular chunky fragments. From the model, one may derive the surface energy loss at impact, the remaining velocity at any depth of penetration, and the distribution of energy deposit along the penetration trajectory. All equations and the values of the required constant coefficients are given along with round-by-round comparisons of predicted versus actual penetration-time curves. Author
