Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material. The equation is typically presented as a linear curve of mean stress vs. alternating stress that provides the maximum number of alternating stress cycles a material will … WebAug 8, 2016 · To determine if a part or object is operating in the infinite life region, the Goodman-Haigh diagram is often used. In addition to the cycle amplitude, mean stress is also accounted for in the Goodman-Haigh approach. Elastic Region. In the elastic region (Figure 9), the relationship between stress and strain remains linear. When a cycle is ...
