Application of Chaboche Model in Rocket Thrust Chamber Analysis

Journal of The Institution of Engineers (India): Series C, 2015
Liquid 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.

Temperature dependent representation for Chaboche kinematic hardening model

Materials at High Temperatures, 2014
The 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

Modeling of unixial and biaxial ratcheting of austenitic steel using Chaboche model

World Journal of Engineering, 2012
This 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 ...

Additional Guidance for Inelastic Ratcheting Analysis Using the Chaboche Model

Volume 1: Codes and Standards, 2014
This paper builds on PVP2013-98150 by Kalnins, Rudolph, and Willuweit [1], which documented two calibration processes for determining the parameters of the Chaboche nonlinear kinematic hardening (NLK) material model for stainless steel, and tested the material model using a pressurized cylindrical shell subjected to thermal cycling.

Characterization of the cyclic-plastic behaviour of flexible structures by applying the Chaboche model

Archives of Civil and Mechanical Engineering, 2017
During seismic events, the gravity loads may cause a reduction of the lateral stiffness of structures; inelastic deformations combined with horizontal loads (P-Δ effect) can bring to a state of dynamic instability that obviously influences building safety.

MODIFIED GENETIC ALGORITHM IN CHABOCHE MODEL PARAMETERS IDENTIFICATION

2017
Many of genetic algorithms that are commonly used have a major drawback – they have high computational power requirements, some in CPU time or high memory consumption or some of them both. So modified genetic was developed and in research presented in this paper algorithm was tested in Chaboche material model parameters identification for low-cycle ...

Using the Nonlinear Kinematic Hardening Material Model of Chaboche for Elastic-Plastic Ratcheting Analysis

Volume 1B: Codes and Standards, 2013
Two calibration processes are selected for determining the parameters of the Chaboche nonlinear kinematic hardening (NLK) material model for stainless steel. One process is manual that requires no outside software and the other follows a finite element software.

Chaboche Material Model and Thermo-Mechanical Behaviour of Polymers with Respect to Fatigue

2017
In this paper we want to highlight the chain of linked topics, which are necessary to cover when implementing a fatigue analysis for polymeric materials and/or fibre-reinforced plastics. Starting from experimental observation the time dependency in cyclic loading responses are emphasized by viscoelastic and viscoplastic phenomena in applied material ...
