Ballistic Impact of Textile Structures

Abstract

Previous work on transverse impact of single textile fibers is reviewed and extended to model orthogonal weaves in which fiber crossovers are simplified as pin joints. A DYNAMIC FINITE-ELEMENT COMPUTER TECHNIQUE PREVIOUSLY DEVELOPED FOR SINGLE FIBERS IS EXTENDED TO MODEL THE WOVEN PANEL. Impact of a woven textile panel exhibits substantial differences compared to the equivalent impact of a single fiber: the propagating strain waves experience pervasive and complex interactions because of the fiber crossovers influence. The ballistic energy is mostly deposited in the orthogonal fibers passing through the impact point, while the other fibers are essentially ineffective, which suggests possible improvements in the design of textile structures intended for dynamic impact applications.
