Calibration of Chaboche Model with a Memory Surface [PDF]
This paper points out a sufficient description of the stress-strain behaviour of the Chaboche nonlinear kinematic hardening model only for materials with the Masing's behaviour, regardless of the number of backstress parts.

Thermodynamic Entropy-Based Fatigue Life Assessment Method for Nickel-Based Superalloy GH4169 at Elevated Temperature Considering Cyclic Viscoplasticity [PDF]
This paper develops a thermodynamic entropy-based life prediction model to estimate the low-cycle fatigue (LCF) life of the nickel-based superalloy GH4169 at elevated temperature (650 °C). The gauge section of the specimen was chosen as the thermodynamic

NUMERICAL MODELING OF ELASTO-VISCOPLASTIC CHABOCHE CONSTITUTIVE EQUATIONS USING MSC.MARC
The aim of the present paper is to propose a special kind of finite element procedure for dynamic and static analysis of civil engineering structures (e.g. trusses, beams, shells and spatial structures) including elasto-viscoplastic models. The Chaboche

Effects of the Unified Viscoplastic Formulation and Temperature Terms on the Thermomechanical Behavior of Soldering Materials [PDF]
Solder materials are critical packaging compounds and due to usually weakest melting temperature among packaging constitutive materials, thus, they are frequently subjected to a multitude of physical phenomena: creep, fatigue and combined hardening ...
