Forced oscillations of rods with transverse breathing cracks of great depth are experimentally investigated. The oscillations of the rods are excited by the kinematic embedding motion, which is reproduced using a vibrostand. The results of the analysis of oscillations are presented on the amplitude-frequency characteristics. The Fourier spectra of periodic oscillations are analyzed. Areas of polysemy of oscillations are investigated. Areas of polysemy of oscillations are investigated.


Keywords: forced non-linear oscillations, rod, crack
