Analysis of Influence of Strata Dip Angle on Shear Deformation of Drilling Casing

open access: yesMeikuang Anquan, 2020
Aiming at the shear failure of drilling casing, based on the movement law of overlying strata in coal seam mining, the finite element model of shear deformation of drilling casing is established by ANSYS numerical simulation software, and the effect of ...

Shear Stress and Atherosclerosis

open access: yesMolecules and Cells, 2014
Hemodynamic shear stress, the frictional force acting on vascular endothelial cells, is crucial for endothelial homeostasis under normal physiological conditions. When discussing blood flow effects on various forms of endothelial (dys)function, one considers two flow patterns: steady laminar flow and disturbed flow because endothelial cells respond ...

A comparison of 1D and 2D bedload transport functions under high excess shear stress conditions in laterally constrained gravel-bed rivers: a laboratory study [PDF]

open access: yesEarth Surface Dynamics, 2022
Channel processes under high-magnitude flow events are of central interest to river science and management as they may produce large volumes of sediment transport and geomorphic work. However, bedload transport processes under these conditions are poorly

Shear models and parametric analysis of the PVC geomembrane-cushion interface in a high rock-fill dam.

open access: yesPLoS ONE, 2021
As a type of flexible impermeable material, a PVC geomembrane must be cooperatively used with cushion materials. The contact interface between a PVC geomembrane and cushion easily loses stability.

Shear Stress Biology of the Endothelium

open access: yesAnnals of Biomedical Engineering, 2005
The relationships between blood flow, mechanotransduction, and the localization of arterial lesions can now be advanced by the incorporation of new technologies and the refinement of existing methods in imaging modalities, computational modeling, fluid dynamics, and high throughput genomics and proteomics.

Experimental Study on the Dynamic Modulus and Damping Ratio of Compacted Loess under Circular Dynamic Stress Paths

open access: yesAdvances in Civil Engineering, 2021
Dynamic loads such as earthquakes and traffic will simultaneously generate vertical dynamic stress and horizontal shear stress in the foundation soil. When the vertical dynamic stress amplitude is twice the horizontal shear dynamic stress amplitude, and ...

Shear Stress and VE-Cadherin.

open access: yesArteriosclerosis, thrombosis, and vascular biology, 2018
Objective- Vascular fusion represents an important mechanism of vessel enlargement during development; however, its significance in postnatal vessel enlargement is still unknown. During fusion, 2 adjoining vessels merge to share 1 larger lumen. The aim of this research was to identify the molecular mechanism responsible for vascular fusion.

Direct Measurement of Wall-Shear Stress of Plane Shear Layer with Plasma Synthetic Jet Actuator

open access: yesJournal of Fluid Science and Technology, 2009
One of the useful ways to measure the effect of the flow control devise is to use the wall-shear stress sensor to measure the wall-shear stress directly.

Shear Characteristics and Strength Criterion of Frozen Joints under Different Opening Degrees

open access: yesAdvances in Civil Engineering, 2021
Samples of rock coupling joints were collected from the Jiangluling Tunnel of the G214 line in Qinghai province. Models with surface topographies similar to these joints were manually created. Freezing shear tests under different normal stress conditions
