Approximate determination of vibrodiagnostic parameter of nonlinearity for an elastic body due to the presence of a breathing crack at a subharmonic resonance

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

“…As mentioned earlier [1][2][3][4], the analysis of interrelation between fatigue crack parameters and vibrations of elastic bodies for the purpose of elaborating effective methods of vibrodiagnostics of fatigue damage still attracts researchers' attention. Significant research efforts are focused on the study of the vibration spectrum of an elastic body with a closing crack under super-and subharmonic resonances.…”
