Based on the foregoing, the goal of this proposed project is to develop a novel methodology based on the peridynamic (PD) theory to predict fatigue life of aerospace structures with high fidelity. A new fatigue model will be implemented in PD framework. The model and its implementation in PD will be validated against experimental measurements. A pre- and post- processor with a graphical user interface will be developed under widely distributed commercial FE software. When complete, this approach will enable the designers/engineers to consider complex component geometries under various loading conditions while accounting for multiple cracks exhibiting complex patterns forming non-planar 3-D surfaces.
