The timoshenko beam theory for the static case is equivalent to the euler-bernoulli theory when the last shear force and bending moment have to be specified at.

Linear plate bending and laminate theory 4m020: • bending moment per unit of length along the edge : mb(s) • torsional moment per unit of length along the. So how does a point moment affect the shear force and bending moment diagrams well it has absolutely no effect on the shear force diagram. Static non-linear beam bending analysis bending theory m is the moment at a given cross-section in the beam,. Pure bending kinematics of pure bending: when a bar is subjected to a pure bending moment as shown in the figure it is observed that axial lines bend to form.
