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 ...

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.

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.

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.

Quantitative isothermal phase-field simulations of peritectic phase transformation in FeMn system

open access: yesJournal of Materials Research and Technology, 2016
The present investigation shows quantitative results for the peritectic phase transformation of FeMn alloys utilizing phase-field simulations in 1-D and 2-D. The phase-field method used was based on an adaptation of the proposal of Folch and Plapp [Phys.

Fourier-Spectral Method for the Phase-Field Equations

open access: yesMathematics, 2020
In this paper, we review the Fourier-spectral method for some phase-field models: Allen–Cahn (AC), Cahn–Hilliard (CH), Swift–Hohenberg (SH), phase-field crystal (PFC), and molecular beam epitaxy (MBE) growth.

Simulating hydrogen embrittlement fracture based on phase field method

open access: yesXibei Gongye Daxue Xuebao, 2022
The phase field hydrogen embrittlement fracture model is improved by introducing tension-compression split of strain energy. The numerical formulas of the model are provided, besides, the coupling term of concentration field and displacement field is ...

Phase field methods and dislocations [PDF]

open access: yesActa Materialia, 2003
Abstract We present a general formalism for incorporating dislocations in Phase Field methods (PFM) based on the elastic equivalence between a dislocation loop and a platelet inclusion of specific stress-free strain. Dislocations may be elastically and dynamically coupled to any other field such as a concentration field.

Phase-field method for epitaxial kinetics on surfaces [PDF]

open access: yesThe Journal of Chemical Physics, 2018
We present a procedure for simulating epitaxial growth based on the phase-field method. We consider a basic model in which growth is initiated by a flux of atoms onto a heated surface. The deposited atoms diffuse in the presence of this flux and eventually collide to form islands which grow and decay by the attachment and detachment of migrating atoms ...
