  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. [1]

  3. Bernard Haigh - Wikipedia

    en.wikipedia.org/wiki/Bernard_Haigh

    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. Fatigue (material) - Wikipedia

    en.wikipedia.org/wiki/Fatigue_(material)

    A constant fatigue life (CFL) diagram [34] is useful for the study of stress ratio effect. The Goodman line is a method used to estimate the influence of the mean stress on the fatigue strength. A Constant Fatigue Life (CFL) diagram is useful for stress ratio effect on S-N curve. [35]

  5. Material failure theory - Wikipedia

    en.wikipedia.org/wiki/Material_failure_theory

    Material failure theory is an interdisciplinary field of materials science and solid mechanics which attempts to predict the conditions under which solid materials fail under the action of external loads.

  6. Fatigue testing - Wikipedia

    en.wikipedia.org/wiki/Fatigue_testing

    Fatigue testing is a specialised form of mechanical testing that is performed by applying cyclic loading to a coupon or structure. These tests are used either to generate fatigue life and crack growth data, identify critical locations or demonstrate the safety of a structure that may be susceptible to fatigue.

    Fruitcake. Step one of a fruitcake is soaking pounds of dried fruit until it's plump and filled with bourbon. That takes up to 12 hours. Step two is simple: making and baking the loaves.

  8. Basquin's law - Wikipedia

    en.wikipedia.org/wiki/Basquin's_law

    Basquin's law of fatigue states that the lifetime of the system has a power-law dependence on the external load amplitude, , where the exponent has a strong material dependence. [1] It is useful in expressing S-N relationships .
