Abstract

The behaviour of elastic media containing unsaturated mesocracks is studied in the framework of micromechanics. The cracks are modelled as flat oblate spheroids characterized by their aspect ratio and their orientation. The cracks are filled by two immiscible fluids, namely a liquid and a gas, separated by a capillary interface. Estimates for macroscopic strains induced by drying are derived with the tools of homogenization for disordered media. The case of an isotropic orientation of cracks in the framework of the dilute approximation is considered. It is shown thatwhen the aspect ratio is small enough, taking into account the geometrical nonlinearity brings out a change of the sign of the volumic strain induced by drying with regard to the results of the linear approach.
