Similarity solutions for unsteady shear-stress-driven flow of Newtonian and power-law fluids : slender rivulets and dry patches [PDF]

open access: yes, 2011
Unsteady flow of a thin film of a Newtonian fluid or a non-Newtonian power-law fluid with power-law index N driven by a constant shear stress applied at the free surface, on a plane inclined at an angle α to the horizontal, is considered.

Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman [PDF]

open access: yes, 2005
Knowledge of the spatial characteristics of stress and fractures in reservoirs is important for optimising production and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better ...

Evaluation of Design Provisions for Horizontal Shear Strength in Composite Precast Concrete Beams with Different Interface Conditions

open access: yesApplied Sciences, 2021
In a precast concrete (PC) composite beam, the horizontal interface between the PC beam and the cast-in-place (CIP) slab is located either on the compression side or on the tensile side of the cross-section. If the CIP slab is on the compression side, it

Mechanical Analysis of the Failure Characteristics of Stope Floor Induced by Mining and Confined Aquifer

open access: yesShock and Vibration, 2021
Mining above confined aquifer has become an important task for water inrush prevention in China. To study the failure characteristics of stope floor along the strike, a mechanical model under combined action of mining and confined aquifer was constructed,

Numerical simulation of hydraulic fracture propagation in fractured reservoir using global cohesive zone method

open access: yesFrontiers in Physics, 2023
Natural fractures in reservoirs have a significant influence on hydraulic fracturing propagation. However, existing analyses have neglected the effect of natural fracture deformation parameters, including crack normal stiffness and shear stiffness on ...

Relative significance of shear stress and horizontal pressure gradients on sediment mobility in the inner surf and swash zone

open access: yes, 2021
Puleo, Jack A.The swash zone and inner surf zones are often the most dynamic regions of the beach in terms of sediment transport processes that govern the morphological change of the shoreline.

Design of horizontal shear strain instrument for co-estimation of soil stress-strain [PDF]

open access: yesE3S Web of Conferences, 2020
This study aimed to design and fabricate the horizontal shear strain transducer (HST) for measuring the soil strain under the agricultural machinery traffic by using a rotary potentiometer which was an angular strain change detector. The angular movable mechanism was calibrated and evaluated the characteristics of the instrument in the laboratory, and ...
