Dear all,

Note in PVElite:

For ASME Division 1, the hydrotest allowable stress is 1.3 times the ambient allowable stress for the material. When the vessel is tested, the largest circumferential stress should not exceed this value. If you wish to use 90 percent of the ambient yield stress instead of 1.3 the ambient allowable, then you can check this box.

If i take 90 percent of yield as allowable during hydrotest,what considerations regarding deformation?
