Abstract Scope |
Traditional approaches to using additively manufactured components in load bearing applications involve the fabrication and testing of many identical components. This negates one of the greatest benefits of additive manufacturing, i.e. the ability to quickly and cheaply fabricate one-off components. To address this challenge predictive modeling must be harnessed, particularly for high cycle fatigue performance, where mechanical testing requires significant resources and produces stochastic results.
High cycle fatigue failure is difficult to predict because it can depend nonlinearly on many parameters and their history. This has motivated a succession of fatigue models with ever increasing mechanistic fidelity, raising the question of: what level of mechanistic detail is required to sufficiently predict the performance of AM Ti-6Al-4V components? In this talk, I will give my perspective on this question, building from a decade of AM Ti-6Al-4V fatigue modeling and experimentation across scales. |
