Form factors for circular sections under combined bending and axial load
Abstract:ESDU 18002 presents form factor curves to calculate the maximum permissible bending moments for circular sections. For circular sections, the presence of axial loading, in addition to bending, reduces the permissible bending moment. An estimate of the effect of an axial load acting in this sense on the permissible bending moment of circular sections may be made by use of the form factor curves. The form factor in this Data Item incorporates the Ramberg-Osgood formula to define the stress-strain curve of the material.
