Abstract

This paper presentsa resistance testof a composite plate to the impact load of a bullet. A 9 [mm] caliber bullet hits a three-layer plate made of Kevlar 49 material. For this case of contact analysis, a numerical simulation was performed based on the finite element method. The simulation was conductedin the Abaqus software. It is an explicit dynamic analysis with a high-velocity impact. The simulation was controlled by the VUMAT subroutine written in the FORTRAN programming language. The prediction of plate damage was based on the Hashin criteria, defined in the subroutine. The goal of the paper is to analyze the setting of the composite plate in the form of material selection and orientation of the layers with regard tobullet impact. The resarch results can be applied to ballistic vests, which are intended forpassive protection of the user.
