Fig 612: stress distribution through the thickness of a plate and resultant bending moment plate theory and beam theory plate theory is an approximate theory. So for design purpose of beams, analysis of shear force and bending moment induced are of the at most importance the interesting thing is that you can draw shear. Torsion in structural design 1 introduction developed the theory of general bending and twisting of thin walled beams summing moments about the centroid.

The bending moment varies linearly from one end, where it is 0, and the center where its absolute value is pl / 4, is where the risk of rupture is the most important. Describes bending above the yield stress for elastic materials (mild steel) - references for plastic theory of bending with worked examples.
