| Abstract: | Abstract: The analytical model discussed and formulated in this report focuses on the derivation of a constitutive model for low-porosity, crystalline rocks subjected to compressive stresses. The proposed model is inspired by micromechanical analyses of the kinked-crack mechanism. The report also discusses advantages and limitations of the proposed model listing topics requiring further research. An illustrative example indicates that the suggested methodology leads to a relatively simple and tractable model which was, nevertheless, able to replicate major trends in the deformation process of a Westerly granite specimen in uniaxial compression. All major material parameters in the proposed analytical model are physically identifiable and experimentally measurable. |
