Pattern Formation by Spinodal Decomposition in Ternary Lead-Free Sn-Ag-Cu Solder Alloy

open access: yesMetals, 2022
In comparison to Pb-based solders which have a toxic effect, the tin-silver-copper (SAC) family of alloys have relatively strong reliability and are widely used in the electronics industry.

Phase Field Modeling of Anisotropic Tension Failure of Rock-Like Materials

open access: yesFrontiers in Physics, 2021
The tensile fracture is a widespread feature in rock excavation engineering, such as spalling around an opened tunnel. The phase field method (PFD) is a non-local theory to effectively simulate the quasi-brittle fracture of materials, especially for the ...

The Structure of the Aoki Phase at Weak Coupling [PDF]

open access: yes, 2001
A new method to determine the phase diagram of certain lattice fermionic field theories in the weakly coupled regime is presented. This method involves a new type of weak coupling expansion which is multiplicative rather than additive in nature and ...

Bernaise: A Flexible Framework for Simulating Two-Phase Electrohydrodynamic Flows in Complex Domains

open access: yesFrontiers in Physics, 2019
Bernaise (Binary Electrohydrodynamic Solver) is a flexible high-level finite element solver of two-phase electrohydrodynamic flow in complex geometries. Two-phase flow with electrolytes is relevant across a broad range of systems and scales, from “lab-on-

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 ...

Numerical simulation on movement behavior of dispersed phase droplets of water-in-oil emulsion under electric field

open access: yesYou-qi chuyun, 2022
To explore the demulsification mechanism of emulsion under electric fields, the movement process of dispersed phase droplets in water-in-oil emulsion was simulated with the finite element method.

Phase Field Methods for Binary Recovery [PDF]

open access: yes, 2014
We consider the inverse problem of recovering a binary function from blurred and noisy data. Such problems arise in many applications, for example image processing and optimal control of PDEs. Our formulation is based on the Mumford-Shah model, but with a phase field approximation to the perimeter regularisation.

A mesoscale numerical approach to predict damage behavior in concrete basing on phase field method

open access: yesVietnam Journal of Mechanics, 2021
In this paper, we develop a numerical approach to simulate the 2D complex damage and fracture process of quasi-brittle concrete materials. Based on the phase field theory for the case of elastic isotropic multicomponent materials and the generation ...

Combining phase field crystal methods with a Cahn-Hilliard model for binary alloys [PDF]

open access: yes, 2017
During phase transitions certain properties of a material change, such as composition field and lattice-symmetry distortions. These changes are typically coupled, and affect the microstructures that form in materials.

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.
