A Simple Three-Dimensional Failure Criterion for Jointed Rock Masses under True Triaxial Compression

open access: yesAdvances in Civil Engineering, 2021
The joint configuration and the intermediate principal stress have a significant influence on the strength of rock masses in underground engineering. A simple three-dimensional failure criterion is developed in this study to predict the true triaxial ...

An Extension Failure Criterion for Brittle Rock

open access: yesAdvances in Civil Engineering, 2020
Under the triaxial compressive state, the compressive strain is supposed to happen in the direction of the maximum principal stress, but tensile strain happens in the direction of the minimum principal stress.

Cross-isotropic strength criteria based on spatial plane variation

open access: yesYantu gongcheng xuebao, 2022
The geotechnical materials in nature are affected by the natural sedimentation and often have significant cross-isotropic characteristics. The difference in strength and deformation of structural units of soil in different directions is the main issue ...

Comparison of predicted failure area around the boreholes in the strike-slip faulting stress regime with Hoek-Brown and Fairhurst generalized criteria

open access: yesJournal of Civil Engineering and Management, 2021
Breakout is a shear failure due to compression that forms around the borehole due to stress concentration. In this paper, the breakout theory model is investigated by combining the equilibrium elasticity equations of stress around the borehole with two ...
