Justification of fracture criteria for salt rocks

open access: yesFracture and Structural Integrity, 2022
The study of salt rocks deformation and fracture processes is an essential part of mining parameters justification for mineral salt deposits. The results of uniaxial compression tests on large salt rock specimens are presented as a loading curve and ...

The Generalized Mohr-Coulomb Failure Criterion

open access: yesApplied Sciences, 2023
With the construction of supertall buildings such as high earth dams, the linear envelope of the Mohr-Coulomb (M-C) failure criterion fitted to lower confined pressure would significantly underestimate the loading capacity of foundations, causing a huge ...

Application of the Modified Mohr–Coulomb Yield Criterion in Seismic Numerical Simulation of Tunnels

open access: yesShock and Vibration, 2021
To solve the classical problem that the Mohr–Coulomb yield criterion overestimates the tensile properties of geotechnical materials, a modified Mohr–Coulomb yield criterion that includes both maximum tensile stress theory and smooth processing was ...

Slope stability analysis: Barodesy vs linear elastic – perfectly plastic models [PDF]

open access: yesE3S Web of Conferences, 2019
The results of slope stability analysis are not unique. Different factors of safety are obtained investigating the same slope. The differences result from different constitutive models including different failure surfaces. In this contribution, different

Axisymmetric adaptive lower bound finite element method based on Mohr-Coulomb yield criterion and second-order cone programming

open access: yesYantu gongcheng xuebao, 2023
The axisymmetric Mohr Coulomb yield surfaces have edges and corners in the three-dimensional stress space, which leads to difficulties in numerical calculation.

A Three-Dimensional Elastoplastic Constitutive Model for Geomaterials

open access: yesApplied Sciences, 2023
The Mohr-Coulomb (M-C) failure criterion has been a popular choice for geotechnical analysis because of its simplicity and ease of use. The fact that the M-C criterion disregards the intermediate principal stress’s impact is a significant drawback.
