Effect of Wall Shear Stress Gradient on Cells: Distribution of Deformation and Rotation [PDF]
The effect of wall shear stress gradient on the deformation and rotation of each cell was investigated in vitro. To make a Couette-type of shear flow, the culture medium fluid was sandwiched with a constant gap between parallel walls: a lower stationary ...

Numerical investigation of blood flow features in intracranial saccular aneurysms
This study aims to provide insight about how the hemodynamic factors change with artery curvature for a developing aneurysm during a cardiac cycle. The aneurysm is investigated in terms of the vortical structure and the shear stress along the curved ...

Blood flow in an artery is a fluid-structure interaction problem. It is widely accepted that aneurysm formation, enlargement and failure are associated with wall shear stress (WSS) which is exerted by flowing blood on the aneurysmal wall.

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Shear stress in smooth trapezoidal channel [PDF]
Laboratory experiments were conducted in smooth trapezoidal channel with side slope 1:1 to measure boundary force and shear stress. Preston tube is used to estimate contribution of wall and bed shear stresses.

This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...
