Behaviour of acceleration waves in a viscoelastic porous medium with a structure. Part II – Linear viscoelastic fluid-saturated porous solid

The influence of a medium structure on the propagation of acceleration wave in a fluid-saturated porous medium has been studied. The medium is composed of a viscoelastic solid skeleton and compressible viscous fluid. It has been found that the acoustic tensor is non-symmetric in the considered case. The medium structure influences viscoelastic attenuation of the longitudinal waves only but does not influence attenuation of the rotational waves.
