The shear gage and compact shear specimen for shear property measurements of composite materials
Techniques for shear property measurements for composite and isotropic materials were investigated. A new strain gage called the shear gage was conceived, designed, and tested for routine shear characterization on notched shear specimens. The shear gage integrates the shear strain in the entire …

Complex shear modulus reconstruction using ultrasound shear-wave imaging
… soft tissue mechanical properties. Ultrasound shear-wave imaging can provide quantitative information about soft tissue mechanical properties, specifically the complex shear modulus. Advancing this field has the potential to bridge molecular, cellular, and tissue biology and to influence …

Single shear vs. double shear for nails in lateral loading
… capacity of nails in single and double shear, and (2) to develop a basis for structural design data for laterally loaded nails in double shear applicable whenever deformation is a governing factor, such as in joints of trussed rafters. The test loads at or near proportional limit show …

Bacteria in shear flow
… of fluid flow: creeping flow in soil, highly sheared flow in bodily conduits, and turbulent flow in rivers, streams, lakes, and oceans, as well as anthropogenic habitats such as bioreactors, heat exchangers and water supply systems. The presence of flow not only affects how bacteria are …

Insulation Impact on Shear Strength of Screw Connections and Shear Strength of Diaphragms
… throughout the world have been conducted on the shear strength of screw connections in cold-formed steel, however, little to no research has been conducted on how various thicknesses of insulation placed between two sheets of steel, such as a steel panel and structural supporting member, affects …

Comparison of direct shear and triaxial tests for measurement of shear strength of sand
To ascertain the shear strength parameters of soils for engineering purposes is fundamental to soil mechanics and basic for designing earth-bearing and earth-retaining structures. Direct shear and triaxial tests are the most popular laboratory methods to determine these parameters. The direct shear …

Fatigue Performance and Shear Demand Distributions of Clustered Shear Connectors in Composite Bridge Girders
… (AASHTO) Bridge Specifications assumes uniform shear flow demands at the steel-concrete interface of composite bridge girders. As stud pitch increases to beyond 24 in or as studs become clustered to account for pre-cast concrete decks, this assumed shear demand distribution may be …

Liquefaction and ring shear device
… necessary in order to apply the high strains and shear strain rates that could replicate those of typical flowslides: In particular, these are required to investigate the behavior of the resistance of the flow, which is termed residual undrained strength (Sur). Preliminary tests by de Alba and …

Reinforced composite masonry shear walls
… masonry panels subjected to gravity and in-plane shear loads are discussed herein. Eleven walls were tested. Each of the walls was made from two wythes of brick-to-brick or brick-to-block, with a nominal 2-inch collar joint. In the first 10 walls, the collar joint was grouted and reinforced with …

Shear relaxations of confined liquids
Ultrathin ($$10$\sp4$ Pa), probably due to interactions with flaws in the monolayers. Dramatic signs of wall slip were observed at large strains even at low pressures.

Strength of welded shear studs
… were conducted to study the behavior of welded shear studs. Forty-eight solid slab push-out tests were conducted to study how stud tensile strength and concrete properties affect the strength of shear connections. It is shown that raising the tensile strength of a shear connector actually has an …

Internal hydraulic jumps with upstream shear
Internal hydraulic jumps in flows with upstream shear are investigated numerically and theoretically. The role of upstream shear has not previously been thoroughly investigated, although it is important in many oceanographic flows such as exchange flows and stratified flow over topography. Several …

Shear flow instabilities in stratified magnetohydrodynamics
Shear flows are ubiquitous in nature and man-made settings and they play a fundamental role in the mixing and transition to turbulence of fluid flow. Shear flow instabilities of electrically-conducting fluids play a critical role in the dynamics of astrophysical objects, such as planets, stars, …

Parametric study of timber shear walls
Timber shear walls comprise the vertical element of the lateral force resisting system in many low-rise buildings in North America. A typical shear wall consists of a solid panel product connected to a light timber frame with either a dowel-type fastener, such as nails, or elastomeric adhesives. …
