AWG ERIF Test Case 4: Steel Projectile Impacts Kevlar Fabric

Animation: Test Case 4 Animation
Description: Kevlar is a ballistic fabric with exceptionally high resistance to perforation. Due to its lightweight and mechanical properties is ideal to be used as containment material in jet engines. Often several layers of fabric are used to offer adequate protection to perforation from projectiles. The material model developed by Arizona State University (ASU) has the capability of modeling multiple layers of Kevlar fabric using multiple fabric plies in a single shell element. The advantage of this approach is reduced computational time (fewer element and contact calculations).
Status: Accepted and currently part of the AWG Test Suite
