stress concentrations at countersink

stress concentrations at countersink

stress concentrations at countersink

(OP)
I am validating a cantilever beam which is bolted on the top edge of a shelve using 2 countersink bolts. And the free hand supports a load like a hanger.

However, when simulating, I am getting high stress concentrations (above yield) around the bolt area.

My constraints are fixed on the countersink face and thru hole face.

What would be the ideal method of constraining a bolted joint? Is this the correct setup?
