I'm running a static simulation with bolted connection using beams, from the contact section. When i solve the simulation, I have a so big stress in the edge of the hole, which is clearly a stress concentrator. Is there any way to improve and eliminate this stress concentrator or should I just ignore this value?.
Thanks in advance.

Are you tieing the vertex of the beam connection to the edge of the hole? A better way would be to create imprints of the bolt heads and tie the vertex to that 'area' instead of an 'edge'. You may find this lesson helpful: Bolt Modeling Connections as Beam Elements | Ansys Courses

You are right, I'm applying the beam connection on the edge of the hole. I will try to use the imprint command in SpaceClaim to generate a circular surface around the hole to use that surface to define the beam connection, in the same way that the video that u showed me.
I have a question about the imprint generation, I know how to do it in planar surfaces but I dont know hot to generate this imprint for curve surface like in the model that i have. Could you say me how to do the imprint in curve surfaces?
Thanks in advance.
