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.

DNS of the interaction between a shock wave and a turbulent shear flow: some effects of anisotropy [PDF]
, 2007 Direct numerical simulation is used to study the interaction of a Mach 1.5 shock wave and various types of anisotropic turbulent flows. We compare the interaction of isotropic, axisymmetric and sheared turbulences (sometimes combined), with a specific ...

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Influence of the Field of View on Shear Wave Velocity Estimation
Current Directions in Biomedical Engineering, 2022 Abstract Tissue elasticity contains important information for physicians in diagnosis and treatment, and, e.g., can help in tumor detection because tumors are stiffer than healthy tissue. Ultrasound shear wave elastography imaging (US-SWEI) can be used to estimate tissue stiffness by measuring the velocity of induced shear waves ...

Shear-Wave Velocity to Evaluate In-Situ State of Ottawa Sand
, 1995 : The initial state of a sand, defined by the void ratio and effective mean normal stress, can be used to predict its large-strain response. Laboratory studies have shown that the shear-wave velocity of a sand is controlled primarily by the effective ...
