• Description:
  This grant supported the efforts of the FAA to develop an enhanced life management process, based on probabilistic damage tolerance principles, to address the threat of material or manufacturing anomalies in high-energy rotating components of aircraft engines. Major research products included automated methods for integrity and reliability assessment of production rotors using both 2-D and 3-D finite element models; completion of first-generation capabilities for high-temperature crack growth; methods for incorporating local residual stress effects; new capabilities for fleet risk computations; improved methods for fracture mechanics characterization of cracks in rotors; and multiple new versions of the DARWIN® computer code for technology transfer to industry and the FAA. The efforts facilitate implementation of official advisory material for circular holes and support evolving methods for surface damage analysis of attachment slots and turned surfaces, while also developing improved analysis methods for inherent anomalies in all materials.
