Crack localization without a prior preparation of the inspected surface can be a possible alternative to penetrant inspection in industrial processes.
Consequently, it can be used to improve vibration based crack detection techniques.
This approach is proposed as a temporary measure to prevent further propagation of the crack before repair of the crack can be done.
The proposed technique can effectively identify the crack positions without a knowledge of structure characteristics or a mathematical model.
Experimental results indicate that the proposed method can detect the crack position effectively
The higher level of analysis can, in some cases, confirm that the structural element containing a crack can still be exploited.
Also, the shape changes during crack propagation can be tracked with ease.
can be used to evaluate the mode mixity at the crack tip.
Finally, crack can be detected automatically.
The method can be generalized to other crack problems without difficulty.
