内容简介：

The courses lecture <<Micromechanics and damage>> presents an introduction of the micromechanics (i.e. homogenization) and its applications to some simplely approximated materials, such as composites with rigid inclusions and porous materials.

The subject of my presentation is twofold: the first objective is to develop and implement extended limit analysis in the context of ductile porous geomaterials whose matrix obeys to a perfectly non-associated plastic laws. This has been observed through a large number of experimentation that many plastic constitutive laws of engineering materials, particularly those of geomaterials, are non-associated.  In the second part, we propose from the micromechanical point of view an analytical model by using the linear comparison composite method to study the elasto-plastic response of porous materials especially subjected to cyclic loading with isotropic and linear kinematic hardening at finite strains. To this end, we use an approximate but numerically efficient decoupled homogenization strategy between the elastic and plastic parts.
