Abstract: Many components in conventional and nuclear power plant, aeroengines, chemical plant etc., operate at temperatures which are high enough for creep to occur. These include plain pipes, pipe bends, branched pipes etc., the ...

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 ...
