Abstract
Innovative research and development leading to a dual-use advanced technology product is proposed. The product is a methodology and associated software for three-dimensional design and life prediction of ceramic matrix composite (CMC) components. Once developed and validated, the methodology would be used in cost effective development of CMC components by the Air Force and its major aerospace engine suppliers. The proposed methodology would be applicable to a broad class of CMCs and components for military and commercial applications. An innovative Physics-Based mechanistic modeling approach is proposed. The approach includes direct consideration of relevant defect and damage mechanisms and environmental degradation. Phase I will include characterization of two and three dimensional deformation and damage in mechanistic model for CMC materials selected by Pratt & Whitney. The models will be validated against benchmark and sub-element test data involving three dimensional stress states. Predictions will be compared with experimental measurements to assess the modeling approach and feasibility for a comprehensive methodology development in Phase II.
