Summary on Grant Application Form |
|
The proposal is aimed at building the foundations for the next generation of fatigue life prediction methodologies. Detailed measurements of plasticity-induced fatigue crack closure and crack growth rates will be undertaken for three-dimensional geometries under non-uniform loading. Finite element modelling will be used to produce a detailed model of crack behaviour, including crack tip plasticity and closure. The predictions of this model will be compared with experimental observations and with results from a simplified two dimensional plane stress and plane strain 'strip-yield' models and with a 'plane yield' model formulated using the eigenstrain method. The proposed work is to be performed in collaboration with the University of Bristol, Rolls Royce plc and British Aerospace (Airbus)EngProg\
