(2018): Modelling the time-dependent behaviour of granular material with hypoplasticity
INT J NUMER ANAL MET. 2018; 42(12): 1331-1345. FullText FullText_BOKU

Abstract:
This paper presents a constitutive model for time-dependent behaviour of granular material. The model consists of 2 parts representing the inviscid and viscous behaviour of granular materials. The inviscid part is a rate-independent hypoplastic constitutive model. The viscous part is represented by a rheological model, which contains a high-order term denoting the strain acceleration. The proposed model is validated by simulating some element tests on granular soils. Our model is able to model not only the non-isotach behaviour but also the 3 creep stages, namely, primary, secondary, and tertiary creep, in a unified way.
