Hi Eddie,

 

The stress at one node might be an artificial one. You can try refinement and the stress will further increase. Generally, stress at fillet is not a singularity. Share the loads and boundary conditions - just to check if there is any load applied just next to the fillet. For the top and bottom layers with shell elements, you may expect similar stress magnitude and they may be higher with respect to the mid-plane level (an analogy is the bending of a cantilever beam where the top and bottom layers will have the same stress magnitude).
