Abstract: This paper is concerned with the development of a methodology for thermomechanical analysis of high temperature, steampressurized P91 pipes in electrical power generation plant under realistic (measured) temperature and ...

Abstract: The high temperature low cycle fatigue behavior of P91 weld metal (WM) and weld joints (crossweld) is presented. Straincontrolled tests have been carried out at 400 آ°C and 500 آ°C. The cyclic behavior of the weld ...

Abstract: Cofiring biomass with traditional fuels is becoming increasingly relevant to thermal power plant operators due to increasingly stringent regulations on greenhouse gas emissions. It has been found that when biomass is ...

Abstract: A serviceaged P91 steel was used to perform an experimental program of cyclic mechanical testing in the temperature range of 400 آ°C–600 آ°C, under isothermal conditions, using both sawtooth and dwell (inclusion of ...

Abstract: The finite element (FE) implementation of a hyperbolic sine unified cyclic viscoplasticity model is presented. The hyperbolic sine flow rule facilitates the identification of strainrate independent material parameters for ...
