Discrete modelling of capillary mechanisms in multi-phase granular media [PDF]

open access: yes, 2009
A numerical study of multi-phase granular materials based upon micro-mechanical modelling is proposed. Discrete element simulations are used to investigate capillary induced effects on the friction properties of a granular assembly in the pendular regime.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

open access: yesDeep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Triaxial Compression Performance Research of Steel Slag Concrete on the Unified Strength Theory

open access: yesApplied Sciences, 2020
To better explore the mechanical properties of steel slag concrete (SSC) under triaxial compression, true triaxial tests were performed on SSC with three replacement ratios (30%, 70%, 100%) by a servo-controlled setup (TAWZ-5000/3000).
