A reevaluation of irregular joint shear behavior on the basis of 3D modelling of their morphology - Part Il: Joint Shear Behavior Mechanical Modelling

Abstract : This second part of the paper presents the results of an experimental study on the shear behavior of unfilled natural rock joint replicas in order to consider a renewed approach based on the 3D angular distribution of asperities on the joint mean plane, the 3D surface roughness and the progressive degradation of asperities in relation to the shear displacement and applied normal stress
