During stresses calculation are calculated bending and shear stresses for main points of cross section as far as decisive Huber - Henckey combined stress criteria for whole cross section.
For stresses calculation only follow cross section shapes are supported:

Decisive Huber - Henckey combined stress criteria is calculated as maximal Huber – Henckey stress criteria calculated on each i-th main point of cross section as:
