| 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 ICMD® modeling software can provide reliable property predictions that can significantly lower the amount of testing required while still yielding a robust material property dataset. 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 has recently integrated these tools into user friendly software workflows on the ICMD® platform, and validated the fatigue predictions experimentally for additively manufactured Titanium, Aluminum, and Nickel alloys. |
