Te Goodman and Soderberg criteria are widely used methods for asseming suigue failure in materials subjected to cyclic loaling. These criteria help condiers predict thee lifespan of condients and ensure safety in various applications.

Understanding Únava

Fatigue failure applies when a material is subjected to repeted stress cycles, learing to tho te iniciation and growth of crags over time. This process can result in sudden failure even if thee applied stresses are below thee material 's ultimate e ateth.

The Goodman Criterion

Te Goodman criterion provides a graphical metodol to evaluate te the safety of a contriment under combine static and cyclic stresses. It relates thee mean stress and alternating stress to thee material 's endurance limit.

Te Goodman line is definited by te equation:

The Soderberg Criterion

Te Soderberg criterion offers a more conservative accach by considering the yield criterth instead of the ultimáte criterion. It is often used for safety- kritial contribuents.

Aplikation in Design

Inženýři usej these criteria to determinate safe stress levels for contrients under cyclic loading. By percepting thee stresses on tha e Goodman or Soderberg diagram, they can assess whether a design is with in safe limits.
