Abstract

In this contribution, an original constitutive model is proposed to describe, within a unique framework, the initiation, the propagation and the arrest phases of landslides. The model is built such that it is enable to model in one hand a stable stage with an elasto-plastic behaviour, and in another hand a viscous dominated behaviour. The transition between the two behaviours is performed by means of the second order work stability criterion. This model is applied for an undrained triaxial test, in which the stress invariant consistently falls after the transition.
