The answer to your question is a good theory for composite beams. It is known simplistic composite beam theories based on E-B type or Timoshenko type assumptions fail to accurately predict the stiffness, let alone the 3D stress within the structure. The problem is solved using the variational asymptotic method, which is also implemented in the computer code VABS .
