Shear Flow Calculator

Calculate shear flow in thin-walled open and closed sections for beam shear and torsion loading.

Applied transverse shear force.
N
First moment of area of the portion above the point of interest.
mm³
Second moment of area of the entire section about neutral axis.
mm⁴
Thickness of the thin wall at the point of interest.
