Titanium Damage Tolerant Design Data for Propulsion Systems

Abstract

The program consisted of crack growth threshold, crack growth rate, and fracture toughness testing for each alloy plus strain controlled low cycle fatigue crack initiation testing on Ti 8-1-1. The effects of stress ratio, cyclic frequency, and temperature were determined, providing a broad data base for damage tolerant design of titanium gas turbine engine components.
