Beam Problem

Hello all,

I am trying to obtain the normal stresses in a beam subjected to a bending moment. The ratio of the length to thickness of the beam is approximately 3. 8. Will Euller-Bernoulli beam theory provide reasonable results for the normal stresses (using flexural formula)? Is there a formula similar to the flexural formula that considers the effect of transverse shear (timoshenko theory), to compute the normal stresses?

I would appreciate any insights on this problem.

Best Regards,
