Abstract：The numerical model of concrete which contains the internal defects is established based on the traditional random aggregate model. The model was partitioned into three parts, and based on the Conduplicate-line damage evolvement model, the distribution law of damage, strain and stress under three different kinds of impact load was discussed, and the Quantitative Research was made. The relationship of mesoscopic damage and macroscopic crack evolution was built. This research provides an auxiliary role for both the physical test and engineering practice of concrete material.
