Reply To: I have question about stress concentration or singularity

Hi

Yes there seems to be a singularity there (you can verify it by doing a mesh study).

Perhaps try as you suggest, but I do not know if that will completely resolve this.

In most cases one can refine the mesh and look away from that singular corner  and one will see that the stresses are ok some elements away from there (stress singularity).

See this article for some guidance – hope this helps.
