Abstract

To enhance ballistic protection, this paper explores the benefits of granular materials compared to traditional materials used in this field. Currently, ballistic protection employs various materials either individually or in combination, such as armored steels, ceramic layers, composite materials, and granular structures. This study investigates the interaction of projectiles with each type of material, as well as the effects of combining different material layers. Granular materials consist of macroscopic particles, each with its own degrees of freedom. Collisions between these particles transfer energy from the solid body to individual particles, leading to energy dissipation that can halt the motion of particles within the granular material. The primary objective of this research is to analyze the results of projectile impacts on various material obstacles using a mathematical model for image processing.
