摘要：
A numerical model of concrete containing internal defects was established based on the traditional random aggregate model. The model was partitioned into three parts, and based on the conduplicate-line damage evolution model, the distribution law of damage, strain and stress under three different kinds of impact load was discussed, and the results were described quantitatively. The relationship between mesoscopic damage and macroscopic crack evolution was built. The results provided a reference for both physical tests and engineering application of concrete material.
