| Abstract Scope |
Fatigue of AM components is a major challenge in the adoption of AM across many industries. Developing and qualifying fatigue critical components for use in highly regulated industries like aerospace and biomedical requires manufacturing and testing of a significant number of test coupons. This process is highly time consuming and expensive. QuesTek’s ICMDŽ modeling software can provide reliable property predictions that can significantly lower the amount of testing required while still yielding a robust material property dataset. Utilizing ICME, QuesTek has developed microstructure-sensitive fatigue models that can account for both intrinsic (grain size, grain morphology, phase fractions, texture) and extrinsic (inclusions, roughness, porosity) features that drive fatigue life in engineering alloys. QuesTek uses a fatigue modeling framework combining CPFEM at the mesoscale, with microstructurally small crack propagation and physically long crack propagation algorithms, to predict the full fatigue life from incubation to ultimate fatigue failure in both HCF and LCF. |
