Shear center

The shear center, also called the flexural center or center of twist, is the point in a beam cross-section where a transverse load produces bending without twisting.

Shear forming

Shear forming, also called shear spinning, is a metal forming process that thins a rotating disc over a mandrel with rollers to make axisymmetric parts.

Shear pin

A shear pin is a sacrificial mechanical element joining rotating parts of a drive, sized to break when torque exceeds a calibrated limit, protecting the machinery behind it.

Shear stress transport model

The shear stress transport model is a two-equation turbulence model used in computational fluid dynamics, introduced by F. R. Menter in 1994 to predict boundary layers and flow separation.

Shear test

A shear test is a mechanical test applying shear loading to measure shear strength, stiffness, or failure in metals, composites, adhesives, polymers, and soils, standardized by ASTM methods.

Shear wall

A shear wall is a structural wall designed to resist lateral loads, chiefly wind and earthquakes, often surrounding elevator cores and providing lateral stiffness to high-rise buildings.

Sheared-flow Z-pinch

The sheared-flow Z-pinch, also called a sheared-flow-stabilized or SFS Z-pinch, is a fusion confinement concept where pulsed current compresses plasma and sheared flow suppresses kink instabilities.
