Abstract:
In order to more effectively simulate the failure behavior of concrete materials under strong impact load, using LS-DYNA software and based on HJC model, the finite element model of projectile impact reinforced concrete(RC)plate was established, and the effects of failure type, principal strain, shear strain and stress on the penetration of projectile into concrete and through RC plate were studied. The results show that when failure control parameter FS value is 0 or 1.0-1.5, the projectile body of some models fails to penetrate the RC plate, which is inconsistent with the test phenomenon. When FS value is 0.1-0.9, the residual velocity of projectile penetrating through RC plate decreases with the increase of FS value. When FS value is 0.3-0.8, the simulated residual velocity is in good agreement with the experimental value. As for adding failure criteria to the model, when the principal strain is 0.225-0.275 or the shear strain is 0.4-0.5, the calculated residual velocity of the projectile penetrating through the RC plate at the speeds of 606, 746, 1 058 m ·s-1 is closer to the test value. When considering the principal strain failure or shear strain failure or their combined action, the simulation results with FS value of 0.8 are in good agreement with the test. The tensile stress failure criterion is not suitable for thin RC plates subjected to strong impact load.
