The Micro Defect Damage Definition Based on the Effective Damaged Volume

Li Yinping Wang Yuanhan Doctoral Candidate; College of Civil Eng., HUST, Wuhan 430074, China.  
The conceptual deficiency of the traditional definition of damage variable when damage is caused by a multitude of microcracks or/and microvoids is first pointed out and analyzed. Then based on the effective damaged volume, a definition of micro defect damage is proposed, being able to deal with the individual damage units, the evolution of systems of these damage units, and to describing the anisotropic damage of materials with different kinds of defects.
