Based on the Numerical Simulation of Random Aggregate Concrete Model of the Penetration of the Two Material Models

Abstract:

Based on the micromechanics principle, establish concrete random aggregate, constitutive model choose HJC model and K&C model, numerical Simulation for the part of the S.J.Hanchak projectile penetrating into concrete targets test. Through the bullets remaining projectile velocity and target plate failure compared, it is concluded that Concrete mesostructure uneven impact of its macro mechanics; flaking and spallation phenomena on the HJC model simulation of the target body front and back by the impact appears less effective, and K&C model is in good agreement with the experimental conditions; K&C model is a simple and effective way to predict the dynamic response of the projectile penetrating into concrete targets.
