Pipe fitting pressure simulation

Hi all,

 

I'm working on a project where I need to simulate a pipe fitting under pressure (see below) and would like some advice on how to set up the most realistic simulation scenario.

We can assume it's fastened at both ends in the corresponding female threaded connections and is subjected to 620 bar (62MPa).

To reduce the processing load I've sectioned it @ 60 deg and simplified the threads (see below).

I've applied 4 slider/roller fixtures to the part. On each and and on each cut face. I then applied the 62 MPa normal to the bore.

I'm feeling this is too simplistic as the fitting will likely stretch ever so slightly in the real world.

Any comments are welcome and appreciated.

 

Thanks in advance,

Marc
