WebAug 29, 2024 · Corrections must be made to account for mean stress. Typically, more damage is accumulated when the product is under a tensile mean stress, while less damage is accumulated under compressive mean stress. This article covers the Mean Stress Correction process using the Goodman diagram and Stress Ratio (R). Article … WebMay 3, 2012 · A technique is proposed here in-which limits are placed on the mean stress correction, directly analogous to those used in the creation of so-called modified Goodman diagrams. This technique has been successfully applied at PSM to improve the accuracy of life prediction without increasing the risk of non conservatism.
