Jan 1, 2006 · The aim of the present paper is to present the existing Chaboche model variants and describe its scientific and engineering applications.

Jun 1, 2023 · The Chaboche combined isotropic/kinematic hardening model has gained wide popularity due to its outstanding description on cyclic stress-strain relations of different structural metals.

The Chaboche material model is a commonly used model for simulating the behavior of stainless steels, aluminum, nickel, and copper alloys [3,4,5,6,7]. However, it is characterized by a set of parameters that cannot be measured directly from experimental data, such …

Jan 1, 2011 · Chaboche 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.

In this section, the Chaboche nonlinear kinematic hardening model will be used to determine material constants to accurately fit the input experimental data.

Feb 28, 2008 · A correct modeling of cyclic elasto-plastic behavior can be exploited in low-cycle fatigue life investigation as well as in manufacturing problems related to springback prediction. The chosen formulation has been proposed by Chaboche, and it is implemented in most of the commercial codes used for nonlinear FEM simulations.

Jan 1, 2017 · Modelling of cyclic plasticity and viscoplasticity of a nickel-based alloy using Chaboche constitutive equations

May 26, 2024 · The Chaboche model, named after its developer Jean-Louis Chaboche, is a cornerstone in the field of material science, particularly in understanding and predicting the behavior of materials under cyclic loading.

Each of the backstress terms of the Chaboche model have the form of an Armstrong-Frederick rule, where the parameters represent a plastic modulus and serve as the parameters for history dependence.

The updated Voce-Chaobche material model combines the nonlinear kinematic hardening rule of Chaboche with an updated formulation of the nonlinear isotropic hardening law of Voce. This constitutive model is intended to be used for mild steels subjected to cyclic loading.
