Periodically-arrayed ferroelectric nanostructures induced by strain concentration in SrTiO3

open access: yesNihon Kikai Gakkai ronbunshu, 2019
Ferroelectric behavior in mechanically strained SrTiO3 nanoporous is investigated using phase-field models. We find, in the paraelectric nanoporous, periodically arrayed ferroelectric nano-region is formed due to strain concentration, namely ...

A Generalized Phase-Field System

open access: yesJournal of Mathematical Analysis and Applications, 1999
The authors consider the problem \((\Omega\) bounded domain in \(\mathbb{R}^N\) with \(C^2\)-boundary) \[ \begin{aligned} {\partial u\over\partial t}+l {\partial \varphi\over\partial t}=\Delta u+f(x,t), \quad & (x,t)\in Q:=\Omega \times(0,T),\\ {\partial\varphi \over\partial t}=\Delta\varphi+ F(x,t,\varphi) +u,\quad & (x,t)\in Q,\\ {\partial u\over ...

Lectures on Phase Field [PDF]

open access: yes, 2023
This open access textbook fills a gap, in that it introduces readers to the theory and applications of the Phase-Field technique. Phase Field, over the years, has emerged as a standard tool for materials research, just as the Finite-Element technique has in structure mechanics.

Athermal resistance to phase interface motion due to precipitates: A phase field study [PDF]

open access: yes, 2022
Athermal resistance to the motion of a phase interface due to a precipitate is investigated. The coupled phase field and elasticity equations are solved for the phase transformation (PT).

A Phase Field Approach to Trabecular Bone Remodeling

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
We introduce a continuous modeling approach which combines elastic response of the trabecular bone structure with the concentration of signaling molecules within the bone and a mechanism for concentration dependent local bone formation and resorption. In

Phase-field modelling of molecular dynamics with diffusive motions [PDF]

open access: yes, 2022
Recently, phase-field modelling has been expanded to the molecular scale. However, such atomistic phase-field simulation cannot treat diffusive motions of molecules so far. Here, we modify phase-field modelling of molecular dynamics to include rigid body

Lattice Phase Field Model for Nanomaterials [PDF]

open access: yesMaterials, 2021
The lattice phase field model is developed to simulate microstructures of nanoscale materials. The grid spacing in simulation is rescaled and restricted to the lattice parameter of real materials. Two possible approaches are used to solve the phase field equations at the length scale of lattice parameter.
