1. Maximum stress theory• Both ASME Code Section VIII Division 1, andSection I use the maximum stress theory as abasis for design.• The maximum principal stress is determinedapplying this theory
2. Maximum Shear Stress Theory• Yielding will start at a point when themaximum shear stress at that point reachesone-half <strong>of</strong> the the uniaxial yield strength.• Both ASME Code, Section VIII, Division 2 andASME Code, Section III, utilize the maximumshear stress criterion.
