Is the friction angle the maximum slope of a free surface of a non cohesive material?
A. Modaressi, P. Evesque
Starting from a symmetric triangular pile with a horizontal basis and rotating the basis in the vertical plane, we have determined the evolution of the stress distribution as a fun…
Limits of isotropic plastic deformation of Bangkok clay
P. Evesque
A model assuming incremental plastic isotropic response has been recently proposed to model the deformation of isotropic packing of grains, in the small-strain range. It is used he…
p=constant compression on loose Hostun sand: The case of an anisotropic response
P. Evesque
Experimental data from axially symmetric compression test at constant mean pressure p on Hostun sand from Flavigny experiments on loose sands are used to study the validity of an "…
Experimental Proof of the Existence of a Bifurcation Process During the undrained test in Clay
P. Evesque, M. Hattab
Recent papers, based on a new simple incremental modelling which assumes an "isotropic" response, predicts that the trajectory followed during an undrained compression test exhibit…
How to Fit simply Soil Mechanics Behaviour with Incremental Modelling and to Describe Drained Cyclic Behaviours
P. Evesque
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 Poi…
A new non linear mechanism able to generate avalanches based on soil mechanics
P. Evesque
We propose a general mechanism based on soil mechanics concepts, such as dilatancy and friction, to explain the fact that avalanches stop at an angle smaller than they start: the m…
