Abstract: A method of damage detection to plate structure based on damage index was introduced. The paper firstly simplified this structure to multi plate combination。From the view of strain energy, deduced the expression of damage index about modal shape, then calculated modal shape before and after damage of two different circumstances and got curved surface of damage index. At last, verified this method using experiment. This method is useful to detect single damage position of plate structure, and can be refereed for multi damages detection.
