Multi-Scale Computational Models for Fatigue Predictions in Polycrystalline Aluminum Alloys
Abstract
The research project will launch an integrated computational modeling program at Johns Hopkins University. The research will address a critical technological need in the fatigue and life prediction of aluminum alloys used in navy aircraft systems by introducing state-of-the-art methods in Computational Mechanics and Computational Materials Science. Building on the previous developments by the PI, the proposed research will develop a comprehensive computational framework involving micro-mechanical deformation and failure analysis to address the challenging issue of fatigue crack nucleation and propagation in polycrystalline microstructures of 7000 series Aluminum alloys, e.g. Al 7075-T6. The research will lead to better prediction of low cycle fatigue (LCF) and high cycle fatigue (HCF) behaviors in these alloys.
