The Influence of Amplitude-Dependent Damping on Vibrodiagnostic Parameters of the Presence of a Closing Crack in a Beam Under Subharmonic Resonance

The paper summarizes the results of approximate calculation of the influence of amplitudedependent dissipation of energy on vibrodiagnostic parameters of the presence of a closing mode I edge crack in beams of rectangular cross-section for different end restrain conditions and different cases of harmonic excitation of subharmonic resonance in any natural mode.
