Acoustic Properties of Isotropic Hypoelastic Materials with Residual Technological Stresses

Abstract:

A linearized statement was used to study the problem of propagation of small perturbations in isotropic uniformly stressed hypoelastic medium. The obtained results allow answering the question on how the initial stress field affects the parameters (velocity, shape, amplitude) of an acoustic impulse and how the impulse parameters depend on a propagation direction. The results show that there is evident similarity between “material anisotropy” initially inherent for instance in crystals and “field anisotropy” induced by a field of internal stresses in isotropic medium.
