Fatigue crack growth in a structure exposed to high temperature
Engineering Failure Analysis(2021)
Abstract
•The damaged jet engine exhaust nozzle’s inner sleeve was analyzed.•Analyzed structure was subjected to thermo-mechanical cyclic loading.•Crack propagation in repaired inner sleeves were simulated and analyzed.•It was determined which type of repair gives longer fatigue life for damaged part.
