Hello,
We’re performing pressure testing on an aluminum pressure vessel. What you’ll see in the attached image is that we have four samples that are tested as follows:
1) Burst test – Pressure increased until unit bursts
2) High pressure / low cycle
3) Low pressure / high cycle
4) Lowest pressure / highest cycles
From busting the first unit, we recorded a pressure of 245 psi. We estimate that units 3 & 4 will be tested below 50 psi (due to facility limitations). We would like to select a pressure for unit #2 such that it will result in a clearly defined, signature plot for the pressure to number of cycles relationship. However, we’re not certain what pressure to designate for point #2, how should we go about determining this?
Thank you in advance!
