Webrole. Timoshenko beam theory is applicable only for beams in which shear lag is insignificant. This implies that Timoshenko beam theory considers shear deformation, but that it should be small in quantity. A number of finite element analyses have been reported for vibration of Timoshenko beamsls> WebBeam Theory. Timoshenko beam theory relies on the assumption that the distribution of shear stress over the cross-section is a constant. ... The accuracy of such an approximation was determined by comparing the predicted beam displacement with that measured experimentally (shown in Figure 9).
