Micromechanical analysis of kinematic hardening in natural clay [PDF]

International Journal of Plasticity, 2009
This paper presents a micromechanical analysis of the macroscopic behaviour of natural clay. A microstructural stress-strain model for clayey material has been developed which considers clay as a collection of clusters.

Single cell mechanics: stress stiffening and kinematic hardening [PDF]

Physical Review Letters, 2007
Cell mechanical properties are fundamental to the organism but remain poorly understood. We report a comprehensive phenomenological framework for the nonlinear rheology of single fibroblast cells: a superposition of elastic stiffening and viscoplastic ...

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

Analysis of Undrained Seismic Behavior of Shallow Tunnels in Soft Clay Using Nonlinear Kinematic Hardening Model

Applied Sciences, 2020
In this study, a soil–tunnel model for clay under earthquake loading is analyzed, using finite element methods and a kinematic hardening model with the Von Mises failure criterion.

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.
