| Abstract Scope |
Traditionally, aerospace components are treated as monolithic structures during lifing, wherein microstructural information at individual locations are not necessarily considered. The resulting design is conservative, leading to under usage of the component’s capabilities. To push the design limit, a location-specific lifing framework is developed, which tracks and retrieves manufacturing process and microstructural information at distinct locations for use within a crystal plasticity fatigue life prediction model. A use case for lifing dual microstructure heat treated LSHR turbine disk component is demonstrated at two locations, near the bore (fine grains) and near the rim (coarse grains) regions. We employ the framework to access (a) the grain size statistics and (b) the macroscopic strain fields to inform precise boundary conditions for the crystal plasticity finite-element analysis. The illustrated approach to conduct location-specific predictive analysis of components presents opportunities for tailoring the manufacturing process and resulting microstructures to meet the component’s targeted requirements. |
