shrink fits in Autodesk Simulation Mechanical

shrink fits in Autodesk Simulation Mechanical

(OP)
Greetings,
1. I've been trying to do a shrink fit between a simple cylindrical steel hub (OD = 216 mm)and a solid round steel shaft (dia 140 mm) (using ASM).
2. I've been using solid brick elements for both parts.
3. I draw the parts assembled in inventor with zero mm radial interference
4. I import into ASM
5. I mesh with 8 node bricks, both to say 5 mm element size
6. I change contact to shrink fit/with sliding, friction to 0.15
7. I enter radial interference as 0.18 mm
8. I solve with either sparse solver or automatic
9. I'm getting stresses higher than I thought. I'm expecting 150 N/mm^2 and getting many times this


I've spent quite a while on this. Could someone please give some suggestions on shrink fits using ASM?
Do the solver and contact settings (in the analysis parameter section) affect accuracy?

Regards and thanks
