Approximate Analytical Determination of Vibrodiagnostic Parameters of the Presence of a Closing Crack in Bar Elements Under Subharmonic Resonance

The paper presents the results of approximate calculations of vibrodiagnostic parameters indicating the presence of a closing fatigue edge crack in bars with different boundary conditions versus the crack parameters and exciting load under subharmonic resonance in principal bending mode.
