Standard diagrams for warping torque, bimoment and the St.Venant torsion

The following 6 standard situations are given in the literature (Ref.[2], Ref.[3]).

The value λ is defined as follows :

Mx	the total torque = Mxp + Mxs
Mxp	the torque due to St. Venant
Mxs	the warping torque
Mw	the bimoment
It	the torsional constant
Cm	the warping constant
E	the modulus of elasticity
G	the shear modulus
