Computational simulation of woven fabric subjected to ballistic impacts

Abstract

A novel numerical method to simulate the ballistic impact of woven fabric by small projectiles is presented. The model takes into account various yarn and fabric properties that affects the performance of fabric armour. These properties include the rate-dependent property of the yarns, the fabric woven structure and crimp, as well as inter-yarn friction. The model also takes into account projectile-yarn friction, and can simulate oblique impacts and different projectile geometries. The model uses only 1D elements for the modelling of the fabric, and allows for multiple plies of fabric to be modelled. The spacing between the plies of the fabric can also be adjusted. The model runs on a commercially available finite-element analysis software.
