Abstract: The compression, tensile and damage characteristics of HJC concrete was demonstrated by single brick element compression and tensile simulation, the model was applied to simulate Hanchak perforation experiment，by setting maximal principal strain, equivalent plastic strain and maximal tensile hydrostatic pressure failure index in the simulation, residual velocity and slab failure phenomenon was compared with those from experiment results, both maximal principal strain failure index and maximal tensile hydrostatic pressure failure index obtain good agreement with projectile residual velocity in the experiment than equivalent plastic strain failure index. In addition, equivalent plastic strain failure index show less reasonable spall phenonmon on the surface of slab.
