Summary
When open-section thin walled cantilevers are loaded in simple bending and such that parts of the section become plastic, it is reasonable to suppose that the position of the centre of shear will be affected. This possibility is considered for a semi-circular and a channel section by assuming that the stress-strain relation in the plastic range is sufficiently well summarized by a simple power law and the results of numerical examples are presented.
