ICME-based fatigue life prediction for additive manufactured metallic components

The utilization of additive manufacturing for fatigue rated components is severely hampered by the lack of accurate tools for prediction of fatigue life in additively manufactured parts as a function of material, microstructure, residual stresses, defects, etc that arise as part of the AM process. In the proposed effort, MRL will build on the fatigue modeling tools demonstrated in Phase I to demonstrate part-scale fatigue modeling of AM components using a multi-scale hybrid modeling approach.Ā The results of the Phase II effort will further efforts to accurately predict AM fatigue life and support efforts towards certification of critical components produced by AM.
