Assessment methods for Bree-type ratcheting without the necessity of linearization of stresses and strains

International Journal of Pressure Vessels and Piping, 2007
Pressurized component design codes based on design-by-analysis require the evaluation of thermal ratcheting produced by the combination of primary and cyclic secondary stresses. In the current codes for nuclear power components provide domain categorization type evaluation methods of progressive strain, using Miller's or Bree's diagram.
