PTV Measurement of Turbulent Shear Stress Profiles in a Horizontal Bubbly Channel
Journal of the Visualization Society of Japan, 2004 Particle tracking velocimetry is applied to a bubbly two-phase flow in a horizontal channel to investigate the mechanism of turbulent shear stress reduction using bubbles. We derived three componential stresses to express the phenomenon hidden in the turbulent shear layer and measured them with the PTV data at Re=4×104.

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]
, 1988 A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in ...

Cyclic behaviour of saturated sands subject to previous horizontal shear stresses
, 2011 The dynamic behaviour of saturated sands has been studied from different perspectives. However, most experimental research on this field does not take into account the shear stress conditions existing prior to the application of dynamic loads; i.e., a null initial static shear stress (τo=0) is assumed.

Thermo-mechanical analysis of wellbore stability in ultra-deep formations
Journal of Rock Mechanics and Geotechnical EngineeringWellbore stability is crucial for ultra-deep wells operating under high temperature and high stress conditions. To analyze the effects of thermal shock and horizontal stress on wellbore stability, a series of true triaxial compression experiments and ...

Hydrodynamic origin of Korteweg stresses from shear-induced horizontal buoyancy
Physical Review EA recent study [P. Rajamanickam, ] of non-Boussinesq fluids in narrow channels identified a novel shear-induced horizontal buoyancy force that emerges upon depth-averaging the Navier–Stokes equations. This Letter demonstrates that this force is formally equivalent to the divergence of a Korteweg stress tensor.

Finite-amplitude shear horizontal waves propagating in a pre-stressed layer between two half-spaces [PDF]
International Journal of Solids and Structures, 2013 AbstractThe propagation of finite-amplitude time-harmonic shear horizontal waves, in a pre-stressed compressible elastic layer of finite thickness embedded between two identical compressible elastic half-spaces, is investigated. This is accomplished by combining finite-amplitude linearly polarized inhomogeneous transverse plane wave solutions in the ...

Evaluation of Horizontal Stresses in Soil during Direct Simple Shear by High-Resolution Distributed Fiber Optic Sensing [PDF]
Sensors, 2019 This paper presents an approach for evaluating the horizontal stresses that develop in geotechnical Direct Simple Shear (DSS) tests through the use of high-resolution distributed fiber optic sensing. For this aim, fiber optics were embedded in 3D printed rings used for confining the soil in the test procedure.
