Hey guys,
I am simulating a thick plate with solid mesh elements. In reality the plate is fixed via screws and a loading is applied at the outer edges. For simulation I have created a circular area around the bore holes (split lines), matching the screw head diameter. Then, I fixed these areas, applied a load and ran the simulation. Unfortunately, at the edges of these circles, a singularity is appearing, the stresses get higher the lower the mesh size becomes. How can I prevent that from happening? Is there a better way to model the fixation? ( Also attached some pictures for clarification)
Thanks for helping me, really appreciate it!
