In Femap for a cross-section is it possible to compute Q to be used in shear stress = VQ/It?
The purpose of this article is to discuss whether this is possible.
Femap contains a Shape - Section Property Generator. This convenient graphical cross-section property generator is available for one-dimensional elements such as rods, bars and beams. Femap can automatically compute the cross-section properties and stress recovery locations for common or arbitrary shapes. Such cross-section properties include the area, moments of inertia and torsional constant.
Q the first moment of inertia or statical moment is used in the equation shear stress = VQ/It. It would be useful if Q could also be computed. However unfortunately this is not possible at this time.
