The paper is concerned with dynamic problems of the linear theory of elasticity for anisotropic porous materials according to the Cowin-Nunziato model. In order to take into account the structural damping in elastic media, a new attenuation model which extends the Rayleigh models is used. A set of new finite element schemes is proposed for finding numerical solutions of transient, harmonic, modal and static problems in the context of elastic media with voids. Three-dimensional, plane (plane stress and plane strain) and axisymmetric problems are considered.

Abstract
The paper is concerned with dynamic problems of the linear theory of elasticity for anisotropic porous materials according to the Cowin-Nunziato model. In order to take into account the structural damping in elastic media, a new attenuation model which extends the Rayleigh models is used. A set of new finite element schemes is proposed for finding numerical solutions of transient, harmonic, modal and static problems in the context of elastic media with voids. Three-dimensional, plane (plane stress and plane strain) and axisymmetric problems are considered.File in questo prodotto:
