ASME Section VIII Divsion 2 2010 & 2011 addenda
(OP)
I am trying to find some reasoning/history on why the equations to calculate for Principle Stresses have changed from the Section VIII Division 2 1995 edition to the new Section VIII Division 2 2010, 2011 addenda edition.
Primarily the use of the Natural Log to calculate the Hoop(Circumferential) Membrane Stress in a shell.
I am comparing my principle stress calculations using the 1995 edition with the 2010 edition and the new code returns a higher principle stress.
Any light shined on this would be appreciated.

As vpl pointed out, the 2007 Edition of Division 2 was a major rewrite. Everything was changed. I would recommend that you refer to ASME PTB-1 for a thorough discussion.
