Shear flowFrom Wikipedia, the free encyclopedia

The term shear flow is used in solid mechanics as well as in fluid dynamics. Looselyspeaking, shear flow is defined as:

the gradient of a shear stress force through the body (in solid mechanics);the flow induced by such a force gradient (in a fluid).

In this article the first definition from solid mechanics is used. See Viscosity for a fullertreatment about the term from fluid dynamics.

DimensionsIn solid mechanics, shear flow is given in dimensions of force per length. This correspondsto units of newtons per meter in the SI system and pound-force per foot in the EnglishEngineering and British Gravitational systems.

Shear flow in semi-monocoque structuresThe equation for shear flow in a particular web section of the cross-section of asemi-monocoque structure is:

where

q - the shear flowVy - the shear force perpendicular to the neutral axis x through the entire cross-sectionQx - the first moment of area about the neutral axis x for a particular web section ofthe cross-sectionIx - the second moment of area about the neutral axis x for the entire cross-section
