NUMERICAL MODELING OF THE TENSILE DAMAGE OF CONCRETE UNDER DYNAMIC LOADING

摘要：

The tensile damage model of concrete has been presented in this paper. The damage of concrete is simulated using the improved LTZ-2D code. The computational results have verified that the penetration process is dominated by the compressive response of material, and the final damaged state of the material can be significantly influenced by the tensile strength. Based on the proposed model, finite element simulations of EFP (Explosively-Formed Projectile) and projectile penetration tests for concretes have been carried out and compared to experiments. The crater diameters of both front face and distal face of concrete target against different projectile velocities and the diameter of EFP penetration aperture give good agreement with experiments.
