Abstract
A series of fractional plasticity models have been developed to model the stress-strain behaviour of granular soils by using modified Cam-clay yielding function. However, for granular soil, the stress-dilatancy relationship was state-dependent that was better described by the Cam-clay equation. Therefore, an attempt is made in this study to develop a Cam-clay-based fractional plasticity model where numerical solutions of the model are provided for further potential application. To validate the proposed model, a series of triaxial test results on Toyoura sand are simulated. A good agreement between the model predictions and the corresponding test results is observed.
