Résumé

Governing equations for a one-dimensional, second gradient porous system with a solid-material discontinuity are deduced using an extended Hamilton-Rayleigh variational principle. Darcy-Birnkman dissipation is included in this model, while inertial effects are neglected. The linearized problem is used to study the problem of the consolidation of a soil layer. First and second gradient numerical solutions are compared and discussed. [DOI: 10.1685/CSC09245] About DOI
