DETECTION OF ARBITRARILY ORIENTED MULTIPLE CRACKS IN LONG SHAFTS

Mitra, D M Joglekar S K Maiti M;

Full Article:

A method has been developed for detection of arbitrarily oriented multiple open cracks in a slender shaft or beam of circular section. The method is based on changes in the natural frequencies of torsion vibrations. It has been verified based on finite element data for shafts with two, three and four cracks. Case studies are presented for shafts with fixed-free and free-free end conditions. Maximum error in the prediction of location is 2 % and size is ~23%. The method can be useful for detection of arbitrarily oriented multiple cracks.
