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: 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 ...
