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.

Applied Sciences, 2023 The aim of this paper is to model the elastic–plastic uniaxial behaviour of a quenched and tempered steel. The common Chaboche isotropic kinematic hardening model (CIKH) is introduced, and a physics-based procedure is proposed to determine its parameters.

On the Wellposedness of the Chaboche Model [PDF]
, 1998 We formally state and prove the wellposedness and the local Lipschitz continuity of the multisurface stress-strain law of nonlinear kinematic hardening type due to Chaboche within the space of time-dependent tensor-valued absolutely continuous functions. The results also include the more general case of a continuous family of auxiliary surfaces.

High Temperature Mechanical Constitutive Modeling of a High-Nb TiAl Alloy
Journal of Aeronautical Materials, 2018 Uniaxial tensile, low cycle fatigue, fatigue-creep interaction and creep experiments of a novel high-Nb TiAl alloy (i.e. Ti-45Al-8Nb-0.2W-0.2B-0.02Y (atom fraction/%)) were conducted at 750℃ to obtain its tested data and curves.

Numerical simulation of ratcheting and fatigue behaviour of mitred pipe bends under in-plane bending and internal pressure [PDF]
, 2013 This paper investigates the ratcheting and fatigue behaviour of 90 degree single unreinforced mitred pipe bends subjected to a cyclic in-plane closing moment with a non-zero mean value and constant internal pressure. An experiment was conducted to induce

Comparative study of fatigue assessment of defective material based on affected depth
Comptes Rendus. Mécanique, 2022 In this work, we propose a comparative study of fatigue assessment of artificial surface defects based on affected depth (AD). The defect is assumed to be a void (semi-spherical, elliptical, or circumferential notches) on the surface of a material ...

Chaboche's Viscoplasticity Model for Strain – Space Plasticity
Procedia Engineering, 2017 Abstract To obtain reliable stress and strain fields using finite-element simulations, the applied constitutive equations, in general formulated in terms of evolution equations for the stresses and a set of state variables, that should be able to describe hardening properties as well as micro structural aspects with sufficient accuracy.

Anisotropic behaviour law for sheets used in stamping: A comparative study of steel and aluminium [PDF]
, 2003 For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simulation results are not yet as reliable as those of steel.
