I would like to know how VABS deals with shear correction factors, if there are some. I know that in theory, for a bending beam, shear should be parabolic throughout the cross-section. However I don't know if VABS makes the asumption that it is actually constant, and induces a shear correction factor. If it is the case, how is it calculated ? I hope my quation is clear enough.
Thank you for your e-mail.

VABS does not make any assumptions on the distribution forms of stress. And VABS does not use any assumed shear factors based on the cross-sectional geometry, but users can calculate the shear factor after getting the shear stiffness. The following paper may be helpful.
