Development of PMC Numerical Model for Soil and Stone Mixture
Advances in Civil Engineering, 2021 Soil and stone mixture is widely distributed in China, and its physical and mechanical properties are complex, which has a significant impact on geotechnical engineering. Usually soil and stone mixture shows anisotropic features along or perpendicular to

Nonlinear criteria and the influence of the average principal stress on rocks destruction [PDF]
, 2018 Purpose. Consider possible series methods of Mohr-Coulomb nonlinear criterion that takes into account stresses in the plane of fracture. Investigate the influence of the average principal stress on rocks destruction when cylinder modeling under axial and

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 ...

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

Wellbore Breakouts Prediction from Different Rock Failure Criteria
Journal of Engineering, 2020 One of the wellbore instability problems in vertical wells are breakouts in Zubair oilfield. Breakouts, if exceeds its critical limits will produce problems such as loss circulation which will add to the non-productive time (NPT) thus increasing loss in ...

Considerations on elliptical failure envelope associated to Mohr-Coulomb criterion
IOP Conference Series: Materials Science and Engineering, 2016 Mohr-Coulomb theory is mostly used in civil engineering as it is suitable for soils, rock, concretes, etc., meaning that the theory is generally used for brittle facture of the materials, but there are cases when it matches ductile behaviour also. The failure envelope described by the Mohr-Coulomb criterion is not completely accurate to the real yield ...

A state parameter-dependent constitutive model for sands based on the Mohr-Coulomb failure criterion
Computers and Geotechnics, 2022 Experimental data have demonstrated that a strong relationship exists between the state parameter and the peak strength and dilatancy characteristics of sands. This paper proposes a way of reproducing this behaviour using a modified Mohr-Coulomb failure criterion, which retains its simplicity while improving substantially its modelling capabilities ...

Centrifugal loading finite element method for slope stability under damage-seepage coupling effect
Yantu gongcheng xuebao, 2019 An elasto-plastic damage seepage coupling model for rock based on the Mohr-Coulomb criterion is established to analyze slope stability. The stress return method in the principal stress space is given for the Mohr-Coulomb criterion under damage effect to ...
