Calibration of Chaboche Model with a Memory Surface [PDF]

open access: yesTransactions 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

open access: yesProcedia 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

open access: yesProcedia 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.

Sensitivity and optimisation of the Chaboche plasticity model parameters in strain-life fatigue predictions [PDF]

open access: yesMaterials & Design, 2017
The aerospace industry is widely employing strain-life methodologies for structural fatigue predictions. Under spectrum loading, overloads significantly affect the fatigue, therefore it is very important to accurately account for the cyclic transient deformation phenomena.
