Determining rock elastic parameters using a new true-triaxial-based technique
, 2021 : Rock elastic parameters (e.g., elastic modulus and Poisson’s ratio) are the most critical design features in geotechnical engineering since intact and rock masses generally respond in an elastic fashion up to the yield point when under complex three ...

Development and Validation of a Seismic Design Method for Anchored Retaining Walls
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

A method to determine strength parameters by triaxial testing and 3D rock failure models
Journal of Rock Mechanics and Geotechnical EngineeringEstimating the strength parameters of a chosen rock failure criterion is crucial for rational stability analyses. However, the grid search algorithm applied to true triaxial test data presents challenges that hinder its widespread adoption.

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment
Equine Veterinary Journal, EarlyView.Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.

The true triaxial strength anisotropy of sand [PDF]
Sand exhibits transversely isotropic (TI) characteristics, with its strength properties influenced by the coupling effects of the intermediate principal stress ratio b and the orientation angle δ of the bedding plane (BP) relative to the major principal ...

True triaxial testing of sandstones and shales [PDF]
, 2014 In this study deformational and failure properties of sandstones and shales have been evaluated through laboratory experiments under true triaxial stress conditions. The impacts of intermediate stress and water saturation were investigated.

Equine Veterinary Journal, EarlyView.Abstract Background In clinical practice, lameness evaluation often relies on visual assessment under different examination conditions, including ground and figures, and remains subjective. Although objective symmetry indices provide quantitative measures of gait asymmetry, their interpretation across multiple conditions remains challenging because ...
