WebbBending results from a couple, or a bending moment M, that is applied. Just like torsion, in pure bending there is an axis within the material where the stress and strain are zero. This is referred to as the neutral axis. And, just like torsion, the stress is no longer uniform over the cross section of the structure – it varies.
