Theory of bending of beams
Webb25 okt. 2010 · Abstract The classical theory of the bending of beams is strictly exact if the axis of the beam is straight, the loads are applied only at the ends and the cross section is uniform along the length, which is much larger than any other linear dimension. WebbFor plates, the bending and membrane energies are given by Eqs. (4.73), (4.74) and (4.86), (4.87). The total potential energy is a new concept, and it is de ned as the sum of the drain ... 8.3 Two Formulations for Beams In the bending theory of beams, the total potential energy is = Z l 0 1 2 M dx Z l 0
