Mechanism of nucleation in ferroelastic domain switching

Submitted by mohsenzaeem on Thu, 07/25/2024 - 23:46

research

ferroelastic; nucleation

I am happy to share our newest open access article which is just published in Scripta Materialia. For the first time, the mechanism of domain nucleation during ferroelastic domain switching is revealed by utilizing phase-field simulations. Due to relaxation of strain energy, the coherent domain walls of the surviving domains often form features like steps, crevices and corners, and nucleation of new domains primarily takes place at these sites in a repeated fashion. Our work described the mechanism of ferroelastic domain switching to be independent of the domain wall energy.

Ferroelastic switching in yttria stabilized zirconia: A molecular dynamics study

Submitted by mohsenzaeem on Tue, 07/09/2024 - 00:28

research

Ferroelastic; switching; molecular dynamics; phase transformation

I am happy to share our newest open access article which is published in Computational Materials Science. For the first time, we were able to create the t’ phase of yttria stabilized zirconia from its cubic phase through the process of rapid quenching by utilizing molecular dynamics simulations. The simulation of quenching process followed the experimental procedure, and the results of virtual XRD and RDF were comparable to the actual experiments, verifying the created phases.

Length scale insensitive phase-field fracture methodology for brittle and ductile materials

Submitted by mohsenzaeem on Fri, 06/14/2024 - 05:23

research

fracture; phase-field model; length scale insensitive;

Dear colleagues, I would like to share our new article (open access) that presents length scale insensitive phase-field fracture models for brittle and ductile fracture to address the deficiencies of the widely implemented models which over-estimate crack dissipation.

A phase-field model for study of ferroelastic deformation behavior in yttria stabilized zirconia

Submitted by mohsenzaeem on Tue, 06/11/2024 - 00:32

research

Ferroelasticity; phase-field model; strain rate effect

Dear colleagues, our new article (open access) is just published in Acta Materialia. In this research, we provide new insights into the mechanism of ferroelastic deformation by studying the evolution of domains in different microstructure patterns and under different loading directions and strain rates.
