Theoretical analysis reveals nonlinear acoustic effects and resonance behaviors in a resonator, suggesting insights into acoustic systems.
A theoretical study of nonlinear acoustic effects arising from harmonic excitation of a rod resonator with dislocation hysteresis of Granato-Lucke and linear dissipation has been carried out using the perturbation method. Expressions for the resonance curve, nonlinear losses, and shift of the resonant frequencies and the amplitude of the third harmonic are obtained. A graphical and numerical analysis of the obtained results is carried out.
