Paper Title:
Modelling of Cyclic Plasticity and Viscoplasticity of a Nimonic Alloy 75
  Abstract

Cyclic plasticity and viscoplasticity of a nickel-chromium alloy have been described using the Chaboche unified constitutive model. Experiments have been developed to obtain the full cyclic stress-strain and stress relaxation data at 450°C. A step-by-step method has been used to obtain the initial material parameters, while a non-linear least-square approach has been used to obtain the optimised material parameters. Satisfactory results have been obtained for the simulation of the transient and steady state cyclic stress-strain and stress relaxation behavior.
