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 Induces the Release of an Endothelial Elastase: Role in Integrin alpha(v)beta(3)-Mediated FGF-2 Release [PDF]

open access: yes, 2011
Background/Aims: Laminar shear stress is an important stimulus in the endothelium-dependent control of vascular tone and of vascular remodeling processes.

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 ...

Cutout reinforcements for shear loaded laminate and sandwich composite panels [PDF]

open access: yes, 2008
This paper presents the numerical and experimental studies of shear loaded laminated and sandwich carbon/epoxy composite panels with cutouts and reinforcements aiming at reducing the cutout stress concentration and increasing the buckling stability of

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 viscosity and nonlinear behaviour of whole blood under large amplitude oscillatory shear [PDF]

open access: yes, 2013
We investigated experimentally the rheological behavior of whole human blood subjected to large amplitude oscillatory shear under strain control to assess its nonlinear viscoelastic response.

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

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

A shear-stress responsive nano-container to target critically constricted arteries [PDF]

open access: yes, 2014
Atherosclerosis and associated cardiovascular diseases are the world's biggest cause of mortality. During the acute case of heart attack, vasodilators are administered to open up the constricted artery and allow blood perfusion to the surrounding tissue.

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.
