TO THE QUESTION OF STATING A PROBLEM OF MATHEMATICAL MODELING OF HEAT RELEASE ON WOVEN SAMPLE UNDER ACTING THE IMPACT MOMENTUM OF A PROJECTILE
(pp. 58-58)

Abstract. When interacting of small-arms and ordnance projectiles with composite armor barriers, materials of the barriers are involved in very complex processes that proceed simultaneously, are often interconnected and interdependent and resulting in kinetic energy absorption. Existing quality control methods for armor barriers based on determining penetration depth of a projectile, for example, in plasticine, behind the armor barrier have sufficiently high error and are not always feasible. A remote heat control method is an advanced quality control method for armor barriers. However, its implementation is constrained by lack of adequate mathematical models of the interaction between a projectile and the armor barrier. The present paper proposes a new approach to mathematical modeling of heat release on one of types of armor barrier, viz. on a woven sample, under the action of impact momentum of a projectile. The simulated object is a multilayered medium, each layer of which is a set of two families of interwoven filaments. Kinematic parameters of the interaction, stressed state of filaments and heat release & heat transfer processes are modeled. It is assumed to construct the resolving equations on the basis of the 2nd-kind Lagrange equation, including the work of filament tension forces, frictional forces and inertial forces.

Keywords: quality diagnostics, armor barrier, temperature field, projectile, mathematical modeling.
