Range estimation of horizontal stress of deep rock based on Mohr-Coulomb criterion
Results in Physics, 2019 In-situ stress estimation is of great significance in deep coal mining. The vertical stress of the underground rock mass is generally estimated by the product of the upper cover average specific gravity and its depth, and it is difficult to estimate the ...

A New Unified Solution for Deep Tunnels in Water-Rich Areas considering Pore Water Pressure
Geofluids, 2021 Pore water pressure has an important influence on the stresses and deformation of the surrounding rock of deep tunnels in water-rich areas. In this study, a mechanical model for deep tunnels subjected to a nonuniform stress field in water-rich areas is ...

A Macroscopic Strength Criterion for Isotropic Metals Based on the Concept of Fracture Plane
Metals, 2019 Although the linear Mohr−Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too.

Failure criterion effect on solid production prediction and selection of completion solution
Journal of Rock Mechanics and Geotechnical Engineering, 2017 Production of fines together with reservoir fluid is called solid production. It varies from a few grams or less per ton of reservoir fluid posing only minor problems, to catastrophic amount possibly leading to erosion and complete filling of the ...
