How to Fit simply Soil Mechanics Behaviour with Incremental Modelling and to Describe
Drained Cyclic Behaviours
Abstract: It has been proposed recently a new incremental modelling to
describe the mechanics of soil. It is based on two parameters called the pseudo
Young modulus E=1/Co and the pseudo Poisson coefficient n, which both evolve during compression. Evolution of n is known since it shall fit the Rowe’s law of dilatancy,
but Co has to be evaluated from experiment. In this
paper we proposed a way to evaluate the Co
variation from other mechanical modelling. The way cyclic behaviour of drained
sample can be modelled is also described.
