Computational Analysis of Woven Fabric Impact Based on Hybrid Element Analysis

Abstract:

In this paper, Finite element modeling of the impact of the Kevlar woven fabric using hybrid element analysis (HEA) method has been carried out to find out a suitable ratio between area of solid elements used at impact region and area of shell elements used away from impact region. Three HEA models: about one time, two times and three times of the projectile’s diameter with 200 m/s impact velocities are constructed. The solid and shell elements with variable nodal thickness are joined together using tied interfaces in order to ensure that there are no artificial reflections of the longitudinal wave at the interface. The effect of the different ratio of local area and global area on the ballistic performance of the fabric is discussed.
