Enclosure FEA

Hi,

We are doing one Analysis of an Housing for Explosion proof (Preliminary Design Check). The Housing / Enclosure is Like a Circular one with Threading in the Top portion which is closed with a Lid (Male Threading).

Now we want to analyse the Leakage (radial Displacement) between the Enclosure & Lid Threading.

I done the FEA by creating bonded contact between the Enclosure & Lid Pitch Diameter. But this will not be an real condition & will not give correct results.

So guys if you have any ideas (Experience)to solve it, please share.

Thanks in Advance.

Sachin.
