Abstract: Simulation of both damage development and strain ratchetting in uniaxial loading conditions has been presented for a nickel-based superalloy at 650°C using the unified Chaboche viscoplastic model. A third kinematic hardening component was employed to simulate strain ratchetting; and a damage variable, based on plastic strain development, was also incorporated to simulate the damage evolution behaviour. Good agreement between the model predictions and the experimental results was obtained for both damage evolut… Show more
