Hey, I am simulating the connection of a structure that is being pulled by a chain, according to the drawing
This connection is attached to the rest of the structure (square body) by the bolts. However, I am having some problems with the results. Some of the stresses are very high and do not seem proper. I simulate this case with a fine mesh (element sizes in the bolted contact region were 4x smaller than the pitch distance) and here are some of the results that I got.
Since the stresses are so concentrated in a very specific reason, I am doubting these results. Is someone already experience something similar?
P.S.: Since the simulation with the bolted case takes so long due to the mesh refinement requirement, I also attached the project with a more coarse mesh and with bonded contacts. The results look similar
