Abstract
Results of an experimental study of the effects of amplitude-dependent internal friction (nonlinear loss, resonance frequency shift, and sound-by-sound damping) in an acoustic bar resonator made of sandstone are presented. The measurements were carried out for the first five longitudinal modes of the resonator. The analytical description of the observed effects is performed within the framework of the phenomenological equations of state that include hysteretic and dissipative components of nonlinearity. The parameters of the hysteretic and dissipative components of sandstone nonlinearity are obtained from a comparison of the experimental data with analytical dependences describing the nonlinear effects.
