Non-destructive testing technology of a steel bar with crack are analyzed and discussed based on vibration characteristics method. The natural frequencies, mode shapes and modal curvature modal for crack of steel bar were analyzed using the method of finite element analysis. Thus it is concluded that the modal curvature mode can be better characterization of damage properties. In order to determine crack depth, the mathematical expressions between damage factor and crack depth are constructed through wavelet analysis of curvature mode. The results for the selection of dynamic damage identification index and non-destructive testing of member bar structures for engineering structure have engineering application value.
