Phase Field Simulations of Microstructures in Porous Ferromagnetic Shape Memory Alloy Ni2MnGa

open access: yesMetals, 2023
The magnetic domain structures and martensite microstructures of porous Ni2MnGa Heusler alloys with various circle-shaped and ellipse-shaped pores were systematically studied by the phase field method.

Simulation and Printing of Microdroplets Using Straight Electrode-Based Electrohydrodynamic Jet for Flexible Substrate

open access: yesMicromachines, 2022
Electrohydrodynamic jet (e-jet) printing is a modern and decent fabrication method widely used to print high-resolution versatile microstructures with features down to 10 μm. It is currently difficult to break nanoscale resolution (

An Unsteady Model for Aircraft Icing Based on Tightly-Coupled Method and Phase-Field Method

open access: yesAerospace, 2021
An unsteady tightly-coupled icing model is established in this paper to solve the numerical simulation problem of unsteady aircraft icing. The multi-media fluid of air and droplets is regarded as a single medium fluid with variable material properties ...

The phase field method for geometric moving interfaces and their numerical approximations [PDF]

open access: yesGeometric Partial Differential Equations - Part I, 2019
This chapter surveys recent numerical advances in the phase field method for geometric surface evolution and related geometric nonlinear partial differential equations (PDEs). Instead of describing technical details of various numerical methods and their

A practical phase field method for an elliptic surface PDE [PDF]

open access: yesIMA Journal of Numerical Analysis, 2020
Abstract We consider a diffuse interface approach for solving an elliptic PDE on a given closed hypersurface. The method is based on a (bulk) finite element scheme employing numerical quadrature for the phase field function and hence is very easy to implement compared to other approaches.

Phase-field modeling of frost propagation of cracks for rock mass under frost action

open access: yesYantu gongcheng xuebao, 2023
As the rock masses in cold regions freeze, water in cracks turns into ice and expands in volume, and the mechanical interaction between ice and rock may lead to the frost propagation of cracks.

Phase Field Methods and Dislocationss

open access: yesMRS Proceedings, 2000
We present a general formalism for incorporating dislocations in Phas Field methods. This formalism is based on the elastic equiva;ence betweem a dislocation loop and a platelet inclusion of specific stress-free strain related to the loop Burgers vector and normal.
