Calculated Results vs Test Results
Calculated Results vs Test Results
(OP)
I have a question.
Is is common that the calculated pressure of a vessel as determined by FEA and Division III of Section VIII to be higher than the actual burst pressure?
I have a situation where the calculated pressure was about 6% higher than what the actual burst pressure was. I would think that the burst (rupture) pressure would be higher than the calculated pressure using Division III.
Opinions, similar experiences?

I was reading a report that indicated the calculated failure pressure that was higher than the actual burst pressure when the samples were tested to rupture. I found that to be surprising. I expected the calculated result to be lower than the actual burst pressure, i.e., I expected the formula to include a safety factor that resulted in a maximum pressure that would be lower than the actual test pressure that would cause the test specimen to burst. I thought the calculated values would be slightly more conservative than the actual failure pressure. Silly me and making an assumption.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
