Research on the evolution of the deviatoric stress and control of a gas extraction roadway under mining influence

Environmental Earth Sciences, 2023
Aiming at the considerable deformation of the surrounding rock and the difficulty of supporting a roadway affected by the mining of close-distance coal seams, this paper takes the 10607 gas extraction roadway of the Malan Coal Mine as the subject of the ...

A new three-dimensional rock strength criterion based on shape function in deviatoric plane

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Rock strength criteria are the theoretical grounding of geotechnical design and stability estimation, the Mohr–Coulomb (MC) and Hoek–Brown (HB) criteria are the widely accepted criteria at present, due to their reasonability and unambiguous concept ...

A Deterministic Methodology to Calibrate Pressure-Independent Anisotropic Yield Criteria in Plane Strain Tension Using Finite-Element Analysis

Applied Mechanics, 2022
The yield strength of materials under plane strain deformation is often not characterized experimentally due to difficulties that arise in interpreting the results of plane strain tensile tests.

Generalized Matsuoka–Nakai criterion considering hydrostatic pressure dependence in the brittle–ductile region

Deep Underground Science and Engineering, EarlyView.
A generalized Matsuoka–Nakai criterion is proposed in this study, taking the form of a polynomial function, incorporating two parameters to characterize the evolution of the failure envelope within the deviatoric plane.

Turbulence Closure With Small, Local Neural Networks: Forced Two‐Dimensional and β‐Plane Flows [PDF]

Journal of Advances in Modeling Earth Systems, 2023
We parameterize sub‐grid scale (SGS) fluxes in sinusoidally forced two‐dimensional turbulence on the β‐plane at high Reynolds numbers (Re ∼25,000) using simple 2‐layer convolutional neural networks (CNN) having only O(1000) parameters, two orders of ...

Experimental study on strain accumulation characteristics of saturated remolded loess under pure rotation of the principal stress axis

Frontiers in Ecology and Evolution, 2023
The study conducted a pure rotation test of 720° for saturated remolded Q2 loess under principal stress axis (PSA) rotation when deviatoric stress and the intermediate principal stress ratio are different, also paying attention to examining the changes ...

Anisotropic constitutive model of frozen silty clay capturing ice cementation degradation under high mean stresses

Journal of Materials Research and Technology, 2023
Research results show that comparing to unfrozen soil, frozen soil has more complicated deformation behavior owing to the presence of ice. On the basis of triaxial tests results of frozen silty clay (FSC) at ˗6 °C, due to the ice cementation, the ...
