Hi all

Similar to my other post, I'm trying to simulate a hoop pulling down on a hook with a 50N force.

This is what I've tried to emulate that a hoop sits on those top surfaces.

However, it appears that stress concentrates at the edge of a fillet The magnitude of the stress is up to 200MPa, which exceeds the yield strength of 159MPa.

Any idea to why might that be the case? There should be more material in the fillet, so shouldn't it be a stronger area instead?

Thank you

John
