Thermal Mechanical Fatigue Crack Growth. An Application for Fracture Mechanics Analyses of Gas Turbine Engine Disks.

Abstract

The capability of the existing Hyperbolic Sine Model to accurately or conservatively predict the crack growth in engine components subject to thermal mechanical fatigue (TMF) was investigated. It was determined that existing empirical crack growth models adequately predict TMF crack growth under conditions tested, which reflect the current gas turbine engine Retirement for Cause requirements/applications.
