Abstract
Ballistic Impact is the study of behaviour of ductile targets subjected to projectile impact. In this work, simulation and analysis is done by using the Continuum Damage Mechanics (CDM) model on ballistic impact of steel (IS2062: 2006 GR E410W A) target using a rigid projectile. The Continuum Damage Mechanics model is implemented in ABAQUS/Explicit through a user defined material model subroutine (VUMAT). The developed VUMAT is validated by comparing the simulated results in tensile test with experimental results. The effect of the temperature and the strain rate are included in the hardening model as well as in the damage growth model. A critical damage criteria is used to predict the fracture initiation and spread of fracture is simulated by tracing the path of failed elements.
