  2. Goodman relation - Wikipedia

    en.wikipedia.org/wiki/Goodman_relation

    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.

    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]

  4. Material failure theory - Wikipedia

    en.wikipedia.org/wiki/Material_failure_theory

    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.

  9. Fatigue limit - Wikipedia

    en.wikipedia.org/wiki/Fatigue_limit

    The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. [1] Some metals such as ferrous alloys and titanium alloys have a distinct limit, [ 2 ] whereas others such as aluminium and copper do not and will eventually fail even from ...
