Analysis of Fatigue Indicator Parameters for Ti-6Al-4V microstructures using extreme value statistics in the transition fatigue regime

• Study of transition fatigue response of Ti-6Al-4V microstructures for fatigue crack formation. • Generated 4800 simulated microstructures, encompassing ~1,440,000 grains of Ti-6Al-4V. • Probable fatigue crack formation grains are primary-α phase for two R ratios for applied strain. Extreme value (EV) statistics have been previously utilized to model the tails of distributions of computed Fatigue Indicator Parameters (FIPs) to provide a method...
