Available results of novel experimental tests carried out under non-isothermal partially saturated conditions motivate the present study. The goal is to enhance an elastic-plastic model proposed by the authors and to assess its predictive capability with respect to temperature changes. The model is cast within the constitutive framework for partially saturated soils which uses Bishop’s stress and suction as main variables governing the volumetric response of the material.

Abstract
Available results of novel experimental tests carried out under non-isothermal partially saturated conditions motivate the present study. The goal is to enhance an elastic-plastic model proposed by the authors and to assess its predictive capability with respect to temperature changes. The model is cast within the constitutive framework for partially saturated soils which uses Bishop’s stress and suction as main variables governing the volumetric response of the material. The main features of the proposed formulation are illustrated with the aid of some numerical results.File in questo prodotto:
