Abstract
The paper describes the mechanical behavior of two linear isotropic poroe- lastic solids, bonded together by a thin plate-like layer, constituted by a linear isotropic poroelastic material, by means of an asymptotic analysis. After defining a small parameter ε, which will tend to zero, associated with the thickness and the constitutive coefficients of the intermediate layer, we characterize three different limit models and their associated limit problems, the so-called soft, hard and rigid poroelastic interface models, respectively. Moreover, we identify the non classical transmission conditions at the interface between the two three-dimensional bodies in terms of the jump of the stresses, increment of fluid, pressure and displacements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
