Thermodynamically Consistent Model of Damage in Laminated Rocks

Article Preview

Abstract:

The phenomenological model of microcracks evolution in laminated rocks was developed under an isothermal approximation. The general form of the constitutive relations of porous media with microcracks was obtained. This form is necessary and sufficient for carrying out the principle of objectivity and the principle of thermodynamic consistency. The approximation of infinitesimal deformations of medium was investigated. The elastic potential of transversal isotropic brittle rocks was constructed. It involves latent energy of damage and terms which characterize elastic energy release due to damage evolution.
