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…

Analyse des marchés locaux du travail : du chômage à l'emploi

Cette étude vise à éclairer le fonctionnement des marchés locaux du travail en analysant les disparités infra-régionales de deux indicateurs de l’état du marché du travail : le taux de sortie du chômage vers l’emploi et le taux de chômage. L’analyse…

Early age behaviour of concrete nuclear containments

A numerical model has been developed to predict early-age cracking for massive concrete structures. Taking into account creep at early-age is essential if one wants to predict quantitatively the induced stresses if autogenous or thermal strains are…

Topology optimization in damage governed low cycle fatigue

Topology optimization is applied here to discuss an optimization problem of fatigue resistance. Fatigue lifetime is maximized by optimizing the shape of a structure in cyclic plasticity combined with Lemaitre damage law. The topology optimization…
