摘要:Multiaxial high cycle fatigue analyses concern many mechanical components in several industries (aircraft, automobile, railway...). Many multiaxial fatigue criteria have been proposed in the literature for metals. This study deals with the integration of fatigue criteria in finite element code by using APDL (ANSYS Parametric Design Language) scripting language. Three criteria have been implemented including Crossland, Dang Van and Vu et al. [6] criteria. The predictions of Vu et al. criterion are in good accordance with the experimental data.
