Experimental analysis of kaolinite particle orientation during triaxial path

Abstract The goal of this study was to analyze the relation between the behaviour of a clayey material at the macroscopic scale and its microfabric evolution. This may lead to a better understanding of macroscopic strain mechanisms especially the…

Non-quadratic Kelvin modes based plasticity criteria for anisotropic materials

Novel (non-quadratic) plasticity criteria based on Kelvin modes are formulated here for anisotropic materials. As an example, such a macroscopic criterion is applied with success to the case of FCC nickel-base single crystals. Indeed, relying on the…

On the use of XFEM within the Arlequin framework for the simulation of crack propagation

The Arlequin method is a generic numerical method that allows, by local superposition and coupling of models, to address multimodel and multiscale mechanical problems. In particular, this method has already been used to super-impose cracked patches…

Experimental study of kaolin particle orientation mechanism

The aim of the experimental study is to analyse the association between the behaviour of a clayey material at the macroscopic level and its local deformation properties. The approach is based on the study of the orientation of the clay particles by…

Évolution de la microtexture d’une matrice kaolinitique sur chemin triaxial axisymétrique

The goal in this work is to understand how the microfabric of a kaolinitic matrix evolves when it is submitted to an axisymmetric triaxial loading path. The approach consists in doing a triaxial test on slightly overconsolidated saturated specimens,…

Non-saturating nonlinear kinematic hardening laws

To compensate the drawback of most kinematic hardening laws who exhibit hardening saturation, a solution is proposed by replacing the accumulated plastic strain rate in the springback term by a rate related to the kinematic hardening variable itself…

Kelvin decomposition and multiple effective stresses concept in anisotropic materials

The effective stress concept, now classical in continuum damage mechanics, is generalized to the case of an initial anisotropy. In order to be used for both damage–elasticity and damage–(visco-)plasticity coupling, the effective stress should not…
