Abstract:

The principal objective of the proposed Phase I SBIR project is the development of a reliable predictive capability for the evaluation of flaw tolerance in metallic and composite airframe components, given part specifications, material properties, initial flaws, such as voids, inclusions, heterogeneous grain structure and design load spectra. The proposed concept is based on the idea that the safe life methodology and the flaw tolerance approaches fit within the same paradigm if we associate failure initiation and crack propagation events with deformation states of representative volume elements. The paradigm applies to metals and composites. The critical values of the deformation states depend on the material systems under consideration. The methodology of verification and validation will be applied, utilizing existing experimental data and the concept of hierarchic multi-scale models already supported by ESRD's proprietary software StressCheck. Because statistical variations in the manufacture and therefore the mechanical response of structural components are unavoidable, prediction of structural and strength responses must be understood in a statistical sense.
