title = "Viscoplastic modelling of unsaturated geomaterials",
abstract = "In this paper a rate dependent model for unsaturated geomaterials is presented. The formulation and numerical predictions are compared with available experimental results and discussed. The constitutive laws for the description of the time-dependent mechanical behaviour of saturated and unsaturated geomaterials generalize the isotach approach to the elastoplastic strain hardening based constitutive laws for unsaturated soils. The formulation encompasses rate and creep effects together with suction dependency on creep. Some perspectives about the constitutive modelling of time-dependent behaviour of saturated and unsaturated geomaterials, including soft rocks are proposed.",
