“…This model can simulate the ratcheting better than the Armstrong-Frederick (Armstrong and Frederick, 1966) model. It is demonstrated by Bari and Hassan (2000), that the stress-strain hysteresis loop produced by Armstrong-Frederick model deviates significantly from the experiment and the ratcheting strain is also over predicted. Armstrong-Frederick model simulates the same ratcheting loops for all cycles and thus, produces a constant ratcheting rate.…”

Abstract:Ohno-Wang hardening model is an advanced constitutive model to evaluate the cyclic plasticity behaviour of material. This model has capability to simulate uniaxial and biaxial ratcheting response of the material. But, it is required to determine large number of material parameters from several experimental responses in order to simulate this phenomenon. Material parameters for constitutive models are generally determined manually through trial and error approach which is tedious and less accurate. Due to arbitrariness and complexity of cyclic loading, advanced constitutive material models become non-linear and multimodal in functional and parameter space. To overcome this problem, an automated parameter optimisation approach using genetic algorithm has been proposed in the present work to identify Ohno-Wang material parameters of 304LN, stainless steel for uniaxial simulation. Optimisation by this approach has improved the model prediction in uniaxial low cycle and ratcheting fatigue simulations after comparison with the experimental response.
