A unified constitutive model and a continuous damage law are coupled to simulate life analysis for various loading histories on 2(1/4) Cr-1 Mo steel at 600℃℃. The viscoplasticity model and the incremental life prediction law are employed, and their commensurate coupling produces both the inelastic stressstrain response and the damage accumulation, simultaneously and continuously. A life prediction based on stable stress-strain hysteresis or creep deformation analysis is made for creep, fatigue and creep-fatigue loading, and the calculated life shows good correspondence with the experimental data. Subsequently, the aging effect on life prediction is examined.
