Constitutive Model of Duplex Stainless Steel: Experimental Investigation and Genetic Algorithm-Based Parameter Calibration

Buildings
Duplex stainless steel (S22053) is increasingly favoured in construction and marine engineering due to its superior corrosion resistance, toughness, and high strength-to-weight ratio.

Automated calibration of advanced cyclic plasticity model parameters with sensitivity analysis for aluminium alloy 2024-T351

Advances in Mechanical Engineering, 2019
The plasticity models in finite element codes are often not able to describe the cyclic plasticity phenomena satisfactorily. Developing a user-defined material model is a demanding process, challenging especially for industry. Open-source Code_Aster is a

Parameter Calibration of Chaboche Kinematic Hardening Model by Inverse Analysis Using Different Optimization Methods in the Case of Pipe Bending

International Journal of Automotive Science and Technology
Drag link is one of the important parts in steering system used in automotive. The ball joint, ball joint housing, and pipe compose the drag link. In this study, finite element analysis is used to simulate the deformation process. St 52 steel material is

Calibration of Chaboche kinematic hardening model parameters by optimization Chaboche

Drag links are used in the automotive industry mostly, and during painting, their ends are protected against paint by two types of cap productions. While one is machined, the other is cold formed. In this study, a finite element simulation for the deformation process of a drag link’s cap made from St52 alloy is performed.

Spring-Back Evaluation of Stretch Bending Process Based on Chaboche Combined Isotropic-Kinematic Hardening Laws

, 2011
We present a study on spring-back prediction in the stretching bending process using the Chaboche model combined isotropic-kinematic hardening law and Mises yielding criterion, and a material user subroutine (VUMAT, UMAT) program was developed base on ...

Kinematic Hardening Model Comparison of Square Hollow Section Under Cyclic Bending

, 2022
This study compares the different linearity of the kinematic hardening model of the Square Hollow Section (SHS) under cyclic bending loading. Four specimens of a simple support beam cyclically tested in previous research are listed as hot-rolled, hot ...

On the use of the Lemaitre and Chaboche model for the prediction of ductile fracture by void coalescence

, 1998
The model of Lemaitre and Chaboche (LC) (1990) is investigated in the context of a study of ductile fracture of copper by void growth and coalescence. The paper illustrates the fact that a phenomenological model such as the LC model based on a mesoscopic
