| Abstract: | In this paper, the constitutive models of damaged concrete and a new kind fracture criterion for it are inserted into our newly developed finite element code HVP. With the code the 2 D numerical simulations on peretrations of an oval headed projectile into concrete targets are completed, and the concerned results are discussed. The good agreement between the computational results and the experimental ones shows that our physical models, computational method and code are successful. |
