The paper concerns small-amplitude waves in a cylinder of prestressed Mooney material. Analytical and computational techniques are used to construct dispersion curves having real frequencies and complex wave numbers.
While many properties of the curves which hold for classical infinitesimal elasticity are shown to remain valid in the more general context, significant qualitative and quantitative differences are observed as the initial deformation varies. These differences depend upon whether the underlying pure homogeneous deformation corresponds to an extension or a compression along the axis of the cylinder.
