Abstract

The fractional-order plastic flow rule for monotonic loading condition is generalized in this study by analytical derivation to consider the loading and unloading behavior of granular soil under triaxial compression and extension conditions. An improved fractional-order plasticity model is then proposed by using the generalized fractional-order plastic flow rule. The proposed model is validated by simulating a series of experimental results of different granular soils subjected to monotonic and cyclic loading conditions. It is found that unlike the previous model, the proposed model is capable of simulating different kinds of material deformation under monotonic and cyclic loads.
