Generalized Hooke's law for isotropic second gradient materials
F. dell'Isola, G. Sciarra, S. Vidoli
In the spirit of Germain the most general objective stored elastic energy for a second gradient material is deduced using a literature result of Fortuné & Vallée. Linear isotropic…
Second gradient poromechanics
Giulio Sciarra, Francesco dell'Isola, Olivier Coussy
Second gradient theories have been developed in mechanics for treating different phenomena as capillarity in fluids, plasticity and friction in granular materials or shear band def…
A Variational Deduction of Second Gradient Poroelasticity II: An Application to the Consolidation Problem
Angela Madeo, Francesco dell'Isola, Nicoletta Ianiro +1
The second gradient model of poromechanics, introduced in Part I, is here linearized in the neighborhood of a prestressed reference configuration to be applied to the one-dimension…
A Variational Deduction of Second Gradient Poroelasticity Part I: General Theory
Giulio Sciarra, Francesco dell'Isola, Nicoletta Ianiro +1
Second gradient theories have to be used to capture how local micro heterogeneities macroscopically affect the behavior of a continuum. In this paper a configurational space for a…
A solid-fluid mixture model allowing for solid dilatation under external pressure
Giulio Sciarra, Francesco dell'Isola, Kolumban Hutter
A sponge subjected to an increase of the outside fluid pressure expands its volume but nearly mantains its true density and thus gives way to an increase of the interstitial volume…
