In this example, the model is solved for the proof pressure condition of 1950 psig, or 1.5 x max operating pressure and require results for a 2.0 x burst condition. We obtain a Von-Mises stress plot for the proof condition, then scale the results by 2.0 /1.5 = 1.333 to determine the stress for a 2600 psig burst pressure condition:
Under Results:
Create
>Results
>PCL Function
Select Result case >
Enter New result name > Burst Pressure
Select result -> Stress Tensor
New Result Type > scalar
Define PCL expression, Figure 18:
$VONM * 1.333
OK
Apply
Once the new results case is generated, plot the Burst Pressure stress fringe, Figure 19:
