Modelling Highly Energy Absorbing Polyurea-GFRP Composite for Resisting Bullet Impact Using VUMAT-VUSDFLD Subroutine

Category:

Description

The study aims the perforation resistance of the PU-GFRP composite under high velocity impact. Polyurea is modelled as a visco-elastic material model with a strain rate of over 50,000s-1. At this strain rate the material behave as a glass transition material with failure strain of 0.2. The damage in elastomer is modelled using maximum failure strain criteria. GFRP is modelled using Hashin damage criteria with layer thickness of 0.3mm oriented at 0 degree. Results shows that model is capable of stopping bullet travel at over 1500km/hr.
