Cyclic loading of beams based on the Chaboche model

International Journal of Mechanics and Materials in Design, 2010
The 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, 2020
Abstract 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,

Study on Ramberg-Osgood and Chaboche models for 42CrMo4 steel and some approximations

Journal of constructional steel research, 2017
Presented work is focused on experiment-based characterization and modelling of normalized and quenched and tempered low-alloy steel 42CrMo4 subjected to monotonic and cyclic loading and possibility to determine parameters of more complex models from simple ones. The main characteristics of the cyclic Ramberg- Osgood and rate-dependent as well as rate-

A revised Chaboche model from multiscale approach to predict the cyclic behavior of type 316 stainless steel at room temperature

International Journal of Fatigue, 2023
In this work, we propose a revised Chaboche model based on a crystal plasticity multiscale approach. From our experiments, 316L steel exhibits two plasticity characteristics at room temperature during the cyclic loading: varied plastic modulus in strain ...

A strategy to fast determine Chaboche elasto-plastic model parameters by considering ratcheting

International Journal of Pressure Vessels and Piping, 2019
Abstract 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, 2005
The 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 ...

Implementation and application of a temperature-dependent Chaboche model

International Journal of Plasticity, 2015
Abstract 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 ...
