VELOCITY AND SHEAR STRESS IN WAVE BOUNDARY LAYERS
Coastal Engineering Proceedings, 1972 The critical force for the entrainment of sediment on the ocean floor is the maximum, instantaneous shear force. A numerical estimate for the stress is made from the third approximation of a second order boundary layer theory for oscillating laminar flow.

P1138Cardiac shear wave velocity in healthy individuals.
European heart journal. Cardiovascular Imaging, 2016 The closure of the valves generates shear waves in the heart walls. The propagation velocity of shear waves relates to stiffness. This could potentially be used to estimate the stiffness of the myocardium, with huge potential implications in pathologies characterized by a deterioration of the diastolic properties of the left ventricle.

Buneman instability in a magnetized current-carrying plasma with velocity shear
, 2011 Buneman instability is often driven in magnetic reconnection. Understanding how velocity shear in the beams driving the Buneman instability affects the growth and saturation of waves is relevant to turbulence, heating, and diffusion in magnetic ...

Prediction of the Shear Wave Velocity from Compressional Wave Velocity for Gachsaran Formation [PDF]
Acta Geophysica, 2015 Shear and compressional wave velocities, coupled with other petrophysical data, are very important for hydrocarbon reservoir characterization. In situ shear wave velocity (Vs) is measured by some sonic logging tools. Shear velocity coupled with compressional velocity is vitally important in determining geomechanical parameters, identifying the ...
