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…

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…
