Paper presented at the ISRM VII Brazilian Symposium on Rock Mechanics - SBMR 2016, October 19–22, 2016
Paper Number: ISRM-SBMR-2016-15
... - strain relation, a yield surface, a flow rule and a hardening / softening law. In addition, a sand production module is also included by the integration of two primary elements: a sanding onset to determine when is obtained the initiation condition for sand production and a sand production criterion to...

... behavior, which uses the Mohr Coulomb failure criterion. This model emphasizes on the effects near wellbore and integrates a sand erosion criterion as a function of the rock plastic strain and the fluid flow velocity. The entire model takes into account changes in the porosity and permeability as a...

.... Comparatively analysed and mutual verified with results from Hoek-Brown criterion, the parameters of engineering rock masses are comprehensively determined. Finally, the happened failure, token place at the northeast slope in first mining area of Pingshuo East Surface mine, is simulated on a numerical 3D slope...
