Abstrakt: A modified Rayleigh–Plesset equation that takes into account the radial oscillations of a gas bubble covered with a hyperelastic shell and located in a viscoelastic liquid is derived. The shell hyperelasticity was taken into account on the basis of the Mooney–Rivlin model, and the viscoelasticity of the liquid was taken into account using the Kelvin–Voigt model. Numerical calculations have been carried out. The influence of the size of the bubble shell and its rigidity, as well as the shear modulus of the shell and the carrier liquid, on the radial dynamics of a gas bubble in an external acoustic field is analyzed. In a particular case, a comparison of the theory with the experimental data available in the literature is given. [ABSTRACT FROM AUTHOR]
