Mechanics of Impact and Crack Propagation. Phase 1. Development of an Analytical Fracture Model of Projectile Penetration

Abstract

The report is concerned with the application of fracture mechanics theory to the problem of projectile penetration and the situation where an excessive amount of energy is available to damage the target material in the form of fracture followed by crack propagation. The conditions under which this phenomenom takes place depend on several parameters, such as the speed and shape of the projectile and the geometry and material of the target. These conditions have been simulated in the laboratory. The present investigation deals only with the development of an analytical fracture model of the projectile penetration problem using the theory of continuum mechanics.
