Abstract

It is known that Friction has a significant effect in determining the Ballistic impact performance of Woven fabrics. In this paper the ballistic behavior of Twaron Aramid fibers fabrics against High velocity impact of a cylindrical projectile is investigated. Dynamic explicit method using ABAQUS software is utilized to analyze the high-speed impact. For this matter 3D solid elements are used and a VUMAT material model based on maximum stress damage criterion is developed by FORTRAN program. Then using this model, the effects of the Friction between yarns on energy absorption of the fabric is investigated. Results indicate that the amount of stress in the fabric is highly sensitive to the Friction coefficient between the warp and weft fibers. Increasing the Friction between fibers, causes the projectile energy to be distributed among a larger number of threads which increases the penetration time of the projectile in the fibers. In all models, except the case with one layer fabric, higher Friction coefficients cause higher energy absorption in the fabric. Moreover, experimental tests were used to validate the model in this project the results have the agreement with the Correlation coeficient determination of 0. 94, which verifies the accuracy of the simulation.
