Microstructure-sensitive computational multiaxial fatigue of Al 7075-T6 and duplex Ti-6Al-4V
Source abstract
Abstract
Abstract Multiaxial fatigue experiments are expensive and typically require specialized equipment and specimens, but they are essential to support fatigue design of components that experience multiaxial stress states. To leverage limited experimental data, we pursue parametric simulations regarding the influence of multiaxial strain state on extreme value distributions (EVDs) of fatigue crack formation driving force in realistic microstructures. Ensembles of Statistical volume elements (SVEs) for both Al 7075-T6 and Ti-6Al-4V polycrystalline microstructures are subjected to multiaxial cyclic straining to compute EVDs of Fatigue Indicator Parameters (FIPs) that serve as computable surrogate measures of the driving force for fatigue crack formation.
