摘要：
This article established strain characterization of damage factor equation of concrete in elastic stage, and completed the concrete specimens dynamic damage 'freezing in' test. A series of concrete under the strain rate had been gotten, and the damage characteristics of concrete under impact load was analysed. The damage evolution process of concrete material was related to both strain size and strain rate size, and the damage evolution and development and strain rate showedf a power function relation. Then the damage evolution equation used to describe concrete materials could be fitted.
