Two non-destructive inspection (NDI) methods have been used to determine the damage tolerance life prediction of acro-engine turbine discs. For this purpose, low cycle fatigue cracks were examined in the compressor discs of tie bolt holes. The successful implementation of damage tolerance design method strongly depends on the sensitivity and reliability of applied NDI method.
