EXAMPLE: https://sameradeeb-new.srv.ualberta.ca/beam-structures/plane-beam-approximations/#timoshenko-beam-6 role. 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> View timoshenko.pdf from CEED CEE 211 at North South University.

the Timoshenko beam theory retains the assumption that the cross-section remains plane during bending. However, the assumption that it must remain perpendicular to the neutral axis is relaxed. In other words, the Timoshenko beam theory is based on the shear deformation mode in Figure 1d. Figure 1: Shear deformation.

Deformation of a Timoshenko beam (blue) compared with that of an Euler-Bernoulli beam (red). Jun 1, 1995 The Timoshenko beam theory is an extension of the Euler-Bernoulli beam theory to allow for the effect of transverse shear deformation. By combining forces and torques into a six-dimensional vector called a wrench, Hooke's law for the Timoshenko beam can be written in a very simple form. From Dec 11, 2013 The Timoshenko beam subjected to uniform load distribution with different boundary conditions has been already solved analytically.
