(1) Division 1's Pressure Vessels can be Designed with Division 2's Design by Analysis
Elastic-Plastic Stress Analysis Method of Division 2 can be used to qualify Division 1 vessels by elevating the design factors from 2.4 (Division 2) to 3.5 (Division 1).
Stress-strain curves of any materials used in elastic-plastic analysis shall be computed according to ASME, Section VIII, Division 2, Annex 3-D STRENGTH PARAMETERS (2019, page 148). Don’t use measured stress-strain curves.
