Abstract:

This program investigates the seemingly unusual behavior of single crystal airfoil materials. The fatigue initiation processes in single crystal SC materials are significantly more complicated and involved than fatigue initiation and subsequent behavior of a single macrocrack in conventional, isotropic, materials. To understand these differences is the major goal of this project.
