RISApplication of a Creep Damage Constitutive Model for the Rotor of a 1000 MW Ultrasupercritical Steam Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A damagebased creep constitutive model for a wide stress range is applied to the creep analysis of a 1000 MW ultrasupercritical steam turbine, the inlet steam of which reaches 600 آ°C and 35 MPa. In this model, the ...
Finite Element Analysis of the Effects of Thermally Grown Oxide Thickness and Interface Asperity on the Cracking Behavior Between the Thermally Grown Oxide and the Bond Coat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element simulations based on an interface cohesive zone model (CZM) have been developed to mimic the interfacial cracking behavior between the α−Al2O3 thermally grown oxide (TGO) and the aluminum-rich Pt–Al metallic ...
