| Abstract Scope |
A new predictive metallurgy has established an industry-adopted methodology of highly-efficient materials design grounded in the CALPHAD database system now known as the Materials Genome. Initiating in the historic DARPA-AIM program, a long collaboration with Dave McDowell adopting his Fatimi-Socie parametric approach to microstructure sensitive fatigue nucleation has addressed a range of practical alloy design problems including novel process design for healing of damaged inclusions. The approach is now integrated into a fatigue toolkit within the commercial QuesTek ICMD software. Recent application in SMAs has predicted fatigue strength probability distributions directly from nucleant size distributions. Current research addresses direct simulation of multiscale ductile fracture. |
