Shear stress fluctuation measurements using an electrochemical method in pipe flow

Journal of Fluid Science and Technology, 2019
Wall shear stress fluctuations are measured using an electrochemical method in pipe flow. The relationship between the mass transfer and the momentum transfer, studied by Hanratty and Campbell (1983) and the Chilton–Colburn analogy (Chilton and Colburn ...

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Stress overshoot in a simple yield stress fluid: an extensive study combining rheology and velocimetry

, 2011
We report a large amount of experimental data on the stress overshoot phenomenon which takes place during start-up shear flows in a simple yield stress fluid, namely a carbopol microgel.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Investigating the coupling effect of loading rate and initial static shear stress on landslide and soil liquefaction within an energy-based framework

Geoenvironmental Disasters
Background Initial shear stress and loading rate are two critical factors influencing soil mechanical behavior. Their coupled effects, however, remain insufficiently understood, particularly in terms of strength evolution and deformation mechanisms ...

CCM proteins control endothelial β1 integrin dependent response to shear stress

Biology Open, 2014
Hemodynamic shear stress from blood flow on the endothelium critically regulates vascular function in many physiological and pathological situations. Endothelial cells adapt to shear stress by remodeling their cytoskeletal components and subsequently by ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Profile blunting and flow blockage in a yield stress fluid: A molecular dynamics study

, 2008
The flow of a simple glass forming system (a 80:20 binary Lennard-Jones mixture) through a planar channel is studied via molecular dynamics simulations. The flow is driven by an external body force similar to gravity. Previous studies show that the model

Physiological shear stress suppresses apoptosis in human pulmonary microvascular endothelial cells

Physiological Reports
Physiological shear stress contributes to maintaining endothelial cell homeostasis, including suppression of apoptosis. In the pulmonary circulation, diseases such as pulmonary embolism and pulmonary hypertension result in alterations in shear stress ...
