Abstract: In the development of better methods of assessing damage accumulation, one of the requirements is an understanding of the cyclic constitutive behavior of the material. It is known that the ...

Abstract: Aircraft gas turbine components are subjected to severe operating conditions. High temperatures, large thermal strains, and mechanical loads combine to cause the material to undergo significant ...

Abstract: Many high strength alloys that are developed for arduous operating conditions have essentially a two-phase microstructure that is produced by a precipitation-hardening procedure. However, alloys ...

Abstract: Hot flowpath components in aircraft gas turbine engines are subject to a severe operating environment. The large thermal gradients can produce high thermal strains that, when combined with ...

Abstract: The Hot Section Technology (HOST) program has focused on providing methods to solve difficult structural analysis problems. Few structures require as much effort to analyze as the modern aircraft ...
