Deep Underground Science and Engineering, EarlyView.This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Deep Underground Science and Engineering, EarlyView.This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Deep Underground Science and Engineering, EarlyView.To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Triaxial Compression Test on Metal Powders
Journal of the Japan Society of Powder and Powder Metallurgy, 1977 In order to determine the yield criteria for metal powder undergoing compaction and to ascertain the effect of shear stress on the densification, triaxal compression tests were made on iron, copper and aluminium powders under hydrostatic confining pressure up to 600 MPa. The yield criteria for these powders changed gradually from a Mohr-Coulomb type at

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.

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.
