Abstract: (5270 Views)
In this study, factors affecting ballistic performance of fabrics used, including material properties, projectile geometry, boundary conditions, fabric dimensions, multiple plies of fabric armors and friction, has been studied. Ballistic limit was obtained as a criterion of ballistic performance of fabric to identify and compare the effect of the mentioned factor. To obtain the ballistic limit, ballistic tests were performed on the fabric. Also, a finite element model was created using LS-DYNA software and the results of the the simulation of this model show an acceptable agreement between the experimental and numerical analysis. Due to limitation in experimental tests,many of factors affecting performance of armors can be evaluated using this model.
