The application of Chaboche model in uniaxial ratcheting simulations [PDF]
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.

Determination of material properties in the Chaboche unified viscoplasticity model [PDF]
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

Parameter-refreshed Chaboche model for mild steel cyclic plasticity behaviour [PDF]
The development of a steel material model in order to follow the cyclic plastic behaviour is essential in seismic design. The authors present an improved Chaboche model for the cyclic mechanical behaviour of structural steel. The model is based on the combination of nonlinear kinematic and multi-linear isotropic hardening with a parameter refreshing ...

Visco-plastic chaboche model for nickel-based alloys under anisothermal cyclic loading [PDF]
The mechanical behavior of visco-plastic materials such as nickel-based alloys is highly dependent on temperature. Some characteristics such as viscosity, hardening, static recovery, dynamic recovery have more or less influence on the overall behavior depending on the considered temperature.

NUMERICAL MODELING OF ELASTO-VISCOPLASTIC CHABOCHE CONSTITUTIVE EQUATIONS USING MSC.MARC
The aim of the present paper is to propose a special kind of finite element procedure for dynamic and static analysis of civil engineering structures (e.g. trusses, beams, shells and spatial structures) including elasto-viscoplastic models. The Chaboche

On the Wellposedness of the Chaboche Model [PDF]
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.

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.

High Temperature Mechanical Constitutive Modeling of a High-Nb TiAl Alloy
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
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 ...
