Development of Alternate Methods for Establishing Design Margins for ASME Section VIII Division 3
Keyword(s):
The design margin against collapse for Division 3 is based on Nadai’s equation. For high strength materials (the ratio of Sy/Su is more than 0.9) this method is adequate. However for the material with lower ratio of Sy/Su than 0.9 this method has additional margin from entire yielding through the thickness to collapse. The experimental burst test results for closed-end cylinder show the excessive margin for these materials. Therefore the development of alternate methods for establishing design margins for all materials is desirable. In this paper the experimental burst test results, case study of various methods (Div.2 rewrite, current Div.3 and proposed method) for design pressure are investigated.
