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.

BEHAVIOR OF PILE GROUPS UNDER LATERAL LOADS IN SAND SOIL CONSIDERING MOHR-COULOMB AND MODIFIED MOHR-COULOMB CRITERIONS: COMPARATIVE ANALYSIS [PDF]
Journal of Al-Azhar University Engineering Sector, 2021 The behavior of pile groups under lateral loads depends on the soil-structure interaction which is governed by the soil properties and behavior. In the three-dimensional finite element analysis, the prediction of the realistic soil behavior is a complex step in order to capture the realistic pile-soil interaction.

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 ...

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 ...

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 ...

Study on fracture parameter calibration and failure characteristics of rock with hole and crack
Deep Underground Science and Engineering, EarlyView.The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...
