Modelling Cyclic Behaviour of Martensitic Steel with J2 Plasticity and Crystal Plasticity

open access: yesMaterials, 2019
In order to capture the stress-strain response of metallic materials under cyclic loading, it is necessary to consider the cyclic hardening behaviour in the constitutive model. Among different cyclic hardening approaches available in the literature, the Chaboche model proves to be very efficient and convenient to model the kinematic hardening and ...

Experimental investigation on uniaxial cyclic plasticity of cast AZ91 magnesium alloy

open access: yesJournal of Magnesium and Alloys, 2023
The uniaxial cyclic plasticity of cast AZ91 magnesium (Mg) alloy was investigated by conducting a series of cyclic straining and stressing tests at room temperature, and a unique cyclic plasticity (especially for ratchetting) and its physical nature were

Configurational forces in cyclic metal plasticity [PDF]

open access: yesMATEC 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

Plasticity of a Colloidal Polycrystal under Cyclic Shear [PDF]

open access: yesPhysical Review Letters, 2014
We use confocal microscopy and time-resolved light scattering to investigate plasticity in a col- loidal polycrystal, following the evolution of the network of grain boundaries as the sample is submitted to thousands of shear deformation cycles. The grain boundary motion is found to be ballistic, with a velocity distribution function exhibiting non ...

Enhanced strength-plasticity matching of lamellar 1 GPa-grade dual-phase steels via cyclic intercritical quenching

open access: yesJournal of Materials Research and Technology, 2023
In this work, an innovative cyclic intercritical quenching process has been proposed for achieving excellent mechanical properties in terms of strength and plasticity, which results in a lamellar martensitic-ferritic dual-phase steel. The microstructural

Modeling the Strain-Range Dependent Cyclic Hardening of SS304 and 08Ch18N10T Stainless Steel with a Memory Surface

open access: yesMetals, 2019
This paper deals with the development of a cyclic plasticity model suitable for predicting the strain range-dependent behavior of austenitic steels. The proposed cyclic plasticity model uses the virtual back-stress variable corresponding to a cyclically ...

An Identification of the Material Hardening Parameters for Cyclic Loading – Experimental and Numerical Studies [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
This paper presents the results of experimental studies and numerical simulations of the ratcheting for the PA6 aluminum. In the initial determination of the material hardening parameters, the samples were subjected to the symmetrical strain-controlled ...
