Abstract

Abstract

As the continuous improvement of the strength of concrete structure, more and more protective fortifications have chosen concrete as the main building material. On the basis of the smooth particle hydrodynamics method, the TCK-HJC composite constitutive model is proposed to simulate the deformation damage of the concrete target during the penetration process of the rigid conical projectile, and the pseudo-fluid model is used to describe the failed concrete fragments. The deformation process of the conical projectile penetrating into the concrete target under different penetration angles (0°, 60°) were analyzed, and the pressure on the surface of the target was also obtained. The scattering angles of the broken concrete fragments were obtained, and the comparison with experiment shows the simulation result is robust and accurate, which lays a technical foundation for further simulation of the mechanical properties of brittle materials.
