Study on Effect of Thermal-Plastic on Projectile Penetration Concrete Target
(0) In this paper the finite element analysis of the 45# steel projectiles impacting on infinitely thick concrete target was presented. On the basis of the thermal softening effect and damage mechanics, the systematical numerical simulation of the penetration problems about infinitely thick concrete targets was completed. By the numerical computation, the viewpoint that projectile penetration process has limiting velocity was testified, and the mushrooming effect of the steel projectiles penetration concrete targets was observed. The results showed that limiting velocity was 850m/s, above it would appear mushrooming effect and the penetration depth decreased. Thermal field distribution of projectiles with different impact velocity shows that temperature enhanced with the rise of impact velocity. At high impact velocity, significantly increased the temperature of the projectile, the effect of thermal softening cant neglect, and mushrooming effect was obvious.
