3-Dimensional Crack Growth Behavior of Turbine Engine Materials (Preprint)

Abstract

The objective of "3-Dimensional Crack Growth Behavior of Turbine Engine Materials" is to evaluate 2-dimensional and 3-dimensional crack growth and material mechanics in turbine engine components and its corresponding lab specimens under thermomechanical loading configurations. In particular, experiments are conducted on titanium and nickel-base super alloys under simulated engine loading conditions. The resulting residual stresses, the deformation and displacement of the geometry, and the initiation and growth of cracks are analyzed. Such experiments are simulated in finite element analysis (FEA) computer programs. Previous geometries analyzed in this project include turbine disk blades, horseshoe-shaped beams, and dog bone specimens.
