Coupled Thermomechanical Eulerian-Lagrangian Analysis of the KOBO Extrusion Process [PDF]
Archives of Metallurgy and Materials, 2022 Numerical simulations of the KOBO extrusion process are presented in this paper. The coupled thermomechanical Eulerian-Lagrangian approach was applied for the three-dimensional finite element model.

The application of Chaboche model in uniaxial ratcheting simulations [PDF]
Advances in Manufacturing Science and Technology, 2020 Abstract This article presents the application of Chaboche nonlinear kinematic hardening model in simulations of uniaxial ratcheting. First, the symmetrical strain-controlled cyclic tension/compression tests for PA6 aluminum samples were done.

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.

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.

Determination of material properties in the Chaboche unified viscoplasticity model [PDF]
Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2009 An experimental programme of cyclic mechanical testing of a 316 stainless steel, at temperatures up to 600°C, under isothermal conditions, for the identification of material constitutive constants, has been carried out using a thermo-mechanical fatigue (TMF) test machine with induction coil heating. The constitutive model adopted is a modified Chaboche

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.

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.

The Anisotropic Distortional Yield Surface Constitutive Model Based on the Chaboche Cyclic Plastic Model [PDF]
Materials, 2019 Considering the cross effect in the evolution of subsequent yield surfaces for metals, an anisotropic distortional yield surface constitutive model is developed. By introducing an anisotropic distortional hardening function into the isotropic hardening part of the classical Chaboche rate-dependent constitutive model, the plastic-deformation-induced ...
