A Time Multiscale Decomposition in Cyclic Elasto-Plasticity

open access: yesComputers & Mathematics with Applications, 2023
For the numerical simulation of time-dependent problems, recent works suggest the use of a time marching scheme based on a tensorial decomposition of the time axis. This time-separated representation is straightforwardly introduced in the framework of the Proper Generalized Decomposition (PGD).

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

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

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 ...

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 ...

Modelling the cyclic response of structural steel for FEM analyses [PDF]

open access: yesITM Web of Conferences, 2019
Modelling the cyclic response of structural steel plays an important role in the design and performance assessment of steel structures. Up to date, several mathematical models were developed to simulate metal plasticity, but only some of them were ...
