Simulation of CFRP/GFRP Woven Composite Structure Under High Velocity Bullet Impact Using VUMAT (Abaqus + DIGMAT)

Description

The aim of the project is to assess the impact of bullet on the woven composite. VUMAT based on Hashin damage criteria is implemented for CFRP and GFRP composites. Stress wave propagated fast in the direction perpendicular to the direction of fibers. A cohesive contact model based on the traction separation law is implemented on the interface between CFRP and GFRP woven composite.
