Thank you so much sir for your answer. Yes exactly, i'm trying to compare the FEA solution to Euler-Bernoulli deflection equations. My numerical results were different than those which are obtained analytically using Euler-Bernoulli equations and i'm trying to see if this deviation is due to the shear deformation effect.In your opinion sirHow can verify if the deviation between the results was caused by the fact of using a different beam theory (including the shear deformation effect)?
