Acoustical free oscillation NDT method of cracks for turbomachinery

A new vibroacoustical nondestructive testing and evaluation method is proposed. The method uses phase spectral density harmonics of testing object free oscillations as features. New analytical expressions of phase spectral density of testing object free oscillations are received and considered.
