Development of a Self-balanced Rock True Triaxial Compression Instrument [PDF]

open access: yesAmerican Journal of Civil Engineering, 2019
Based on the analysis of the structure and the performance of similar instruments at home and abroad, a Self-balanced Rock True Triaxial Compression instrument (SRT) was developed. For SRT, complex stress realization, based on three-dimensional stress alone control and change; and the self-balanced structure is adopted on the basis of frame design ...

Anisotropic creep model for soft soils [PDF]

open access: yes, 2008
In this paper a new anisotropic model for time-dependent behaviour of soft soils is presented. The formulation is based on a previously developed isotropic creep model, assuming rotated Modified Cam Clay ellipses as contours of volumetric creep strain ...

Failure properties of rocks in true triaxial unloading compressive test

open access: yesTransactions of Nonferrous Metals Society of China, 2015
Slabbing failure often occurs in the surround rock near a deep underground excavation. The mechanism of slabbing failure is still unclear. In order to reveal the influence of the intermediate principal stress (σ2) on slabbing failure, true triaxial unloading compressive test was carried out based on the stress path of the underground engineering ...

Tensor compaction of porous rocks: theory and experimental verification

open access: yesЗаписки Горного института, 2022
Compaction in sedimentary basins has been traditionally regarded as a one-dimensional process that ignores inelastic deformation in directions orthogonal to the active load.

Nonlinear criteria and the influence of the average principal stress on rocks destruction [PDF]

open access: yes, 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

Experimental and Numerical Study of Strength and Failure Behavior of Precracked Marble under True Triaxial Compression

open access: yesShock and Vibration, 2021
Cracks play an important role in evaluating the strength and failure behavior of engineering rock mass. In order to increase the understanding of strength and failure mechanism of precracked rock, crack propagation and coalescence from preexisting cracks

Method Improvement and Effect Analysis of Triaxial Compression Acoustic Emission Test for Coal and Rock

open access: yesAdvances in Civil Engineering, 2019
In the study of the acoustic emission (AE) characteristics of rock samples or coal samples under triaxial compression conditions, most scholars carry out relevant experiments by placing the AE detector on the outer wall of the triaxial chamber of the ...

Solid behavior of anisotropic rigid frictionless bead assemblies [PDF]

open access: yes, 2008
We investigate the structure and mechanical behavior of assemblies of frictionless, nearly rigid equal-sized beads, in the quasistatic limit, by numerical simulation.

Preliminary Study on Post-Peak Behavior and Fracture Characteristics of Hard Rock Under True Triaxial Stress

open access: yesFrontiers in Earth Science, 2022
The post-peak behavior and fracture characteristics of hard rock are correlated with the stability and bearing capacity of engineering rock mass. However, there are relatively few research studies on the post-peak mechanical behavior and fracture ...
