Briefly explain the major differences between Euler-Bernoulli and Timoshenko beam theories?

Solution

In the Euler - Bernoulli beam the deformation at a section, dvo/dx, is just the rotation due to bending only, since the plane section remains normal to the longitudin alaxis.

However, in the Timoshenko beam the section deformation is the sum of two contributions: one is due to bending, dvb/dx, and the other is the shear deformation, dvs/dx .
