Hi guys,
I have a threaded hole 30 mm in diameter on one plate steel a-36 and a 35 mm hole on another plate steel 4140. When I try running a thermal simulation both materials expand at different rates. The holes can be adjusted for a 2 1/2 thousandths of an inch which will cover a lot of stress generated. My problem is that I do not know if solidworks can account for this? When I fix both holes (concentric) I see stresses much higher than the materials resistance which I think is because the materials do not have any tolerance to move and starts generating stresses right away. delta temperature is 200F.

Are you doing a thermal simulation, or are you applying a temperature load in a structural analysis? Do both materials have the same coefficient of thermal expansion?

I don't understand what you mean by this; can you provide further explanation? Are you saying that there's a 0.0025" clearance between the plates?
