An Isotropic Model for Cyclic Plasticity Calibrated on the Whole Shape of Hardening/Softening Evolution Curve

Metals, 2019
This work presents a new isotropic model to describe the cyclic hardening/softening plasticity behavior of metals. The model requires three parameters to be evaluated experimentally.

Study of the Chaboche´s plasticity model complexity influence on the stress and deformation at the high pressure vessel

, 2014
The main aim of this thesis is to define material parameters of Chaboche model of plasticity. Adjustment of the parameters has to correspond to the experimental datas. These datas are represented by an uniaxial strain controlled test curve for fewer than

Modeling of ratcheting - a comparison of the approaches of Chaboche and Ohno & Wang

, 2012
In this Master's Thesis, two ratcheting models, Chaboche and Ohno & Wang (OW), were compared to the Armstrong-Frederick (A-F) model, which is based on nonlinear kinematic hardening.

Experimental Investigation and FE Analysis on Constitutive Relationship of High Strength Aluminum Alloy under Cyclic Loading

Advances in Materials Science and Engineering, 2016
Experiments of 17 high strength aluminum alloy (7A04) specimens were conducted to investigate the constitutive relationship under cyclic loading. The monotonic behavior and hysteretic behavior were focused on and the fracture surface was observed by ...
