Abstract
A multi-crack identification algorithm has been developed based on the forced response from a shaft. Transverse vibrations of a cracked shaft in the two orthogonal planes are analyzed. The presence of cracks in a shaft introduces a local slope discontinuity in the elastic line of the shaft. This slope discontinuity is estimated by approximating the forced response of shaft at consecutive measurement axial locations by a polynomial. The algorithm is tested for numerically simulated responses from the FE modeling of a simply supported shaft having two cracks.
