Calibration of Chaboche Model with a Memory Surface [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 This paper points out a sufficient description of the stress-strain behaviour of the Chaboche nonlinear kinematic hardening model only for materials with the Masing's behaviour, regardless of the number of backstress parts.

Calibration of Chaboche Combined Hardening Model for Large Strain Range
Procedia Manufacturing, 2020 Abstract Variable-loading path and large strain are two typical features in multistage plastic forming process. Material’s yield surface expands and translates simultaneously as the loading path changes, leading to certain transient phenomena such as Bauschinger effect.

An application of Chaboche model to predict uniaxial and multiaxial ratcheting
Procedia Engineering, 2011 AbstractChaboche model can be used to predict the ratcheting phenomenon. The parameter determination of this model to achieve an accurate ratcheting prediction is of great importance. Therefore, the application of an optimization procedure can improve the prediction of this model.
