Service-like Thermo-mechanical Fatigue Tests for the Lifetime Assessment of Turbine Components
A key requirement for modern power generation turbines is a flexible operating capability. One of the main objectives in the design optimization of modern plant is to reduce the time required to reach rated values of power generation during turbine start-up. Significant transient thermal stresses can lead to a complex creep-fatigue damage condition, which has to be evaluated in the lifetime ass...

15 صفحه اولInelastic carrier lifetime in graphene
We consider hot-carrier inelastic scattering due to electron-electron interactions in graphene as functions of carrier energy and density. We calculate the imaginary part of the zero-temperature quasiparticle self-energy for doped graphene utilizing the G0W and random phases approximations. Using the full dynamically screened Coulomb interaction, we obtain the inelastic quasiparticle lifetimes ...
متن کاملLifetime prediction in creep-fatigue environment
The creep-fatigue interaction has been studied and innovative mathematical models are proposed to predict the operating life of aircraft components, specifically gas turbine blades subject to creep-fatigue at high temperatures. The historical evolution of the creep-fatigue lifetime prediction is given in order to place the present study in the context. A literature review of the life estimation...
