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. [1]
Haigh was educated at Allan Glen's School [6] and the University of Glasgow He served as professor of applied mechanics at the Royal Naval College in Greenwich. Haigh is known for his contributions in the fields of metal fatigue, welding and theory of plasticity. He is particularly known for Haigh diagram. [7] [8]
This definition introduces to the fact that material failure can be examined in different scales, from microscopic, to macroscopic. In structural problems, where the structural response may be beyond the initiation of nonlinear material behaviour, material failure is of profound importance for the determination of the integrity of the structure.
Fatigue testing can be used for components such as a coupon or a full-scale test article to determine: the rate of crack growth and fatigue life of components such as a coupon or a full-scale test article. location of critical regions; degree of fail-safety when part of the structure fails
The fatal shooting of a student and a teacher at a private Christian school in Wisconsin on Monday was laden with shock, even for a nation dulled by the horror of repeated school massacres.
