Shell elements stress concentration problem

I am modeling equivalent stress in a bream bracket (picture 1). First, I ran a simulation with solid finite elements, and I get the results shown in picture 2.
Then, I model it using shell elements (picture 3), and I get the results shown in picture 4, which is somehow similar to my solid elements mesh. But if i further refine the mesh (picture 5), it look like I get a stress concentration! Can someone explain me what happened?
Also, since my bracket has fillets (and the shell elements don't take the into account), is the solid elements mesh more reliable?
