I read it but the problem is that, almost 100%, we are not in the plastic deformation area, these are just bolts that are meant to keep the plates together, so the stresses should be way smaller, these are values from catalogues (regarding material and regarding pretension, coming from torque on the nut), so I don´t think we are working in the plastic region, that is why I was asking if my pretensioning was applied wrong and was the cause of these high, not expectable values.
