This paper presents an engineering approach for life prediction of combustor components in an aircraft engine. The challenge is how to apply linear elastic fracture mechanics (LEFM) based methods based on linear elastic fracture mechanics analysis from a practical application perspective to a structure that is under complicated mechanical and thermal loadings that cause stress levels beyond the yield strength. Different crack scenarios of a typical combustor structure are considered. Simplified models are generated to simulate these scenarios for development of analysis methods that are then applied to real combustor structures. Results are presented and compared with those from existing approaches.
