Mechanism of nucleation in ferroelastic domain switching

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.

Ferroelastic switching in yttria stabilized zirconia: A molecular dynamics study

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

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

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.

Localized plastic strain accumulation in shape memory ceramics under cyclic loading

The premature failure of shape memory ceramics (SMCs) under cyclic loading is a critical issue limiting their applications as actuators and thermal protection layers. Martensitic phase transformation (MPT), essential for superelasticity and shape memory functionalities in SMCs, induces localized plastic deformations due to phase expansion. In polycrystalline materials, the accumulation of localized plastic strain serves as the primary mechanism for fatigue crack initiation under cyclic loading.

Atomistic simulation assisted error-inclusive Bayesian machine learning for probabilistically unraveling the mechanical properties of solidified metals

Solidification phenomenon has been an integral part of the manufacturing processes of metals, where the quantification ofstochastic variations and manufacturing uncertainties is critically important. Accurate molecular dynamics (MD) simulations ofmetal solidification and the resulting properties require excessive computational expenses for probabilistic stochastic analyseswhere thousands of random realizations are necessary.

A Mixed Mode Phase-Field Model of Ductile Fracture

We present the first mixed mode phase-field model of ductile fracture. The contribution of crack opening and shearing deformations to the propagation of a crack is expressed by introducing two phase fields. Constitutive relations are then introduced to couple and distinguish these phase fields. Special attention is given to the maximum shear stress and its effect on the development of fractures. The proposed model is validated by tensile testing experiments found in the literature on Al 2024 T-351.

A Phase-Field Model for Interactive Evolution of Phase Transformation and Cracking in Super-Elastic Shape Memory Ceramics

This work presents a modified phase-field model for accurate coupling of phase transformation and cracking in shape memory ceramics. The existing phase-field models underestimate the elastic response at the beginning of the mechanical response. We modified the chemical free energy to control the rate of phase transformation and consequently obtain a physical elastic response before initiation of phase transformation. First, the forward and reverse martensitic phase transformation in a superelastic single crystal 3 mol% yttria-stabilized tetragonal zirconia is studied.

Design of NiTi-based shape memory microcomposites with enhanced elastocaloric performance by a fully thermomechanical coupled phase-field Model

The non-transforming intermetallic Ni3Ti phase generated in NiTi matrix by additive manufacturing was previously reported to create elastocaloric composites with a great coefficient of performance (COP) between 11 and 22 [Hou et al., Science 366 (6469) (2019) 1116–1121]. In this work, we use a fully thermomechanical coupled phase-field model to design microarchitectures with very high COP considering the effects of all the possible non-transforming intermetallics (Ni4Ti3, Ni3Ti, and Ti2Ni) in NiTi.
