Parameter Identification of Chaboche Model for Aluminum Alloy Sheets Based on Differential Evolution Algorithm

Journal of Advanced Engineering and Computation, 2022
Springback prediction is one of the most challenging in finite element analysis for sheet metal forming processes. The demand requests the development of a kinematic hardening model and parameter identification.

Non-Unified Constitutive Models for the Simulation of the Asymmetrical Cyclic Behavior of GH4169 at Elevated Temperatures

Metals, 2022
The tensile, creep, fatigue and creep-fatigue tests of the nickel-based superalloy GH4169 were carried out. According to the deformation characteristics of GH4169 alloy, the Ohno-Karim kinematic model (O-K model) can be used to describe the tensile ...

Configurational forces in cyclic metal plasticity [PDF]

MATEC Web of Conferences, 2019
The configurational force concept is known to describe adequately the crack driving force in linear fracture mechanics. It seems to represent the crack driving force also for the case of elastic-plastic material properties. The latter has been recognized

Modelling the Structure and Anisotropy of London Clay Using the SA_BRICK Model

Applied Sciences, 2023
Several constitutive models had been developed by other researchers to cover the main features of mechanical behaviour of natural overconsolidated clays, such as the nonlinear stress–strain response at small and large strains, and the recent stress ...

On the applicability of multi-surface, two-surface and non-linear kinematic hardening models in multiaxial fatigue

Fracture and Structural Integrity, 2015
In this work, a comparison between NLK and Mróz-Garud’s multi-surface formulations is presented. A unified common notation is introduced to describe the involved equations, showing that the Mróz-Garud model can be regarded as a particular case of the NLK

Influence of Hardening on the Cyclic Plastic Zone Around Crack Tip in Pure Copper CT Specimens [PDF]

Journal of Stress Analysis, 2018
Under cyclic loading, the plastic zone becomes complicated during unloading. The energy-absorbing cyclic plastic zone is a stimulant for crack growth and can be a criterion for determining the damage around the fatigue crack tip.

Effect of the yield surface evolution on the earing defect prediction

Revista de Metalurgia, 2023
Although the prediction of earing in the cup drawing process is considerably related to the yield surface shape, the yield surface evolution is also essential for the final ear form.

Stress integration of the Drucker-Prager material model with kinematic hardening [PDF]

Theoretical and Applied Mechanics, 2015
This paper presents a method for implicit stress integration of the Drucker-Prager material model with kinematic hardening. The stress integration of the material model is conducted using the incremental plasticity method, while the kinematic ...
