Cyclic loading of beams based on the Chaboche model
International Journal of Mechanics and Materials in Design, 2010The time independent non-unified version of the Chaboche constitutive model for the cyclic loading which includes the kinematic and isotropic hardening is discussed in detail. The performance of the Chaboche constitutive model in predicting ratcheting response of CS1026 steel for a broad set of mechanical uniaxial and biaxial loading histories is ...

Numerical implementation of modified Chaboche kinematic hardening model for multiaxial ratcheting
Computers & Structures, 2020Abstract For simulating multiaxial ratcheting behavior, the modified Chaboche kinematic hardening model was numerically implemented by using the framework of a small-strain elastic-plastic theory. Unlike early models, this improved multiaxial model is difficult to implement using finite element methods owing to its complicated constitutive relations,

Abstract Chaboche model is a powerful tool to evaluate the cyclic behavior under different loading conditions using kinematic hardening theory. It can also predict the ratcheting phenomenon. To predict the ratcheting, it is required to determine the material parameters under strain control conditions.

A strategy to fast determine Chaboche elasto-plastic model parameters by considering ratcheting
International Journal of Pressure Vessels and Piping, 2019Abstract Ratcheting simulation for steel material is of importance especially when it is subjected to asymmetrical cyclic loading. A strategy to fast determine the Chaboche elasto-plastic model parameters is proposed by considering the ratcheting effect.

On global stability of the scalar Chaboche models
Nonlinear Analysis: Real World Applications, 2005The Chaboche model for nonlinear kinematic hardening was introduced with the intention to describe rate independent relaxation effects (the so-called ratchetting) in elastoplastic solids. Its main computational difficulty is related to the lack of monotonicity in general, which makes it problematic to apply the techniques developed for generalized ...

Temperature dependent representation for Chaboche kinematic hardening model
Materials at High Temperatures, 2014The assessment of high temperature components under cyclic deformation conditions increasingly relies on determinations of the stress–strain state at the critical location using non-linear finite element analysis. An important consideration in such finite element simulations is the used constitutive model. The Chaboche model has been widely accepted as

Application of Chaboche Model in Rocket Thrust Chamber Analysis
Journal of The Institution of Engineers (India): Series C, 2015Liquid Propellant Rocket Engines are commonly used in space technology. Thrust chamber is one of the most important subsystems of a rocket engine. The thrust chamber generates propulsive thrust force for flight of the rocket by ejection of combustion products at supersonic speeds. Often double walled construction is employed for these chambers.

Implementation and application of a temperature-dependent Chaboche model
International Journal of Plasticity, 2015Abstract The literature shows that shear fracture of advanced high strength steels (AHSS) is affected by strain hardening at large strain, as well as the temperature dependence of flow stress and strain hardening. The role of non-isotropic hardening, such as would be expected to be important in reverse strain paths as encountered during draw-bend ...

Modeling of unixial and biaxial ratcheting of austenitic steel using Chaboche model
World Journal of Engineering, 2012This paper is devoted to the study of the role of identification data base on the prediction of the cyclic behavior of the 304 L stainless steel on ambient temperature. The identification is done using the Chaboche constitutive model. The investigations have been performed with reference to both unixial and biaxial experimental data, strain controlled ...
