Hi,
I am
trying to see if I am doing right when I trying simulate connection between a
body a and a bonnet with bolt and nut
I apply
a pressure of 125 bar inside the bonnet in order to check the bonnet stress and
displacement
The
other fixture I put is to hold the body from 2 side fixed
But
I worry a little bit, because I see a deformation where the bolt head sit. And as
I understand there not supposed to be deformation where the bolt head touch the
bonnet
So,
what are the right fixtures I supposed to
put in order to simulate bolt connection
Thanks,
Oshri
The "best" way to simulate a bolt depends on the goals of the analysis; what are the goals of the analysis? What do you need to simulate? I emphasize need because you rarely need to simulate the exact nature of a bolt.
"I worry a little bit, because I see a deformation where the bolt head sit. And as

Can you explain this a little further? What do you mean by, "deformation where the bolt head sits?" In a real world bolt connect, the material around the bot head can move; in a SW Simulation idealized bolt head, this is not the case because the software is using rigid links to connect the meshed geometry to the beam element representing the bolt.
