Shear flow



Shear flow is:-

in a solid body, the gradient of a shear stress force through the body;
in a fluid, it is the flow induced by such a force gradient - see Viscosity for a fuller treatment.

Dimensions

In solid mechanics, shear flow is given in dimensions of force per length. This corresponds to units of newtons per meter in the SI system and pound-force per foot in the English Engineering and British Gravitational systems.

Shear flow in semi-monocoque structures

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

q = \frac{V_y Q_x}{I_x}
  • q - the shear flow through a particular web section of the cross-section
  • Vy - the shear force perpendicular to the neutral axis x through the entire cross-section
  • Qx - the first moment of area about the neutral axis x for a particular web section of the cross-section
  • Ix - the second moment of area about the neutral axis x for the entire cross-section
