The features of propagation of the acceleration waves in preliminary strained nonlinear elastic solids

The features of propagation of the acceleration waves in a solid that is anisotropic in its actual state, while being isotropic in the natural one, are studied. An algorithm for constructing the acoustic tensor given an initial strain and for elastic potential set in its natural state is derived. Under the most general assumptions on the initial strain, the acoustic tensor is constructed for the following two hyperelastic solids: the Neo – Hookean one and that with modified Mooney – Rivlin potential. It is shown that the regularities of the acceleration waves propagation in the solids differ significantly from conventional properties based on the classical linear theory of elasticity.
