What are Radial Stresses and Curvature Factor?

For a constant cross sectional the radial stress induced by a bending moment in a member is calculated by using this formula


M=bending moment, in lb (N m)
R = radius of curvature at centerline of member, in (mm)
b =width of cross section, in (mm)
d =depth of cross section, in (mm)


When we have a curved portion, curvature factor is introduced and is calculated as

t is the thickness of lamination in (mm)
R is the radius of curvature of lamination in (mm).
