A phase-field model with irradiation-enhanced diffusion for constituent redistribution in U-10wt%Zr metallic fuels

open access: yesFrontiers in Materials, 2022
Constituent redistribution is a unique phenomenon to metal fuels that threatens the safety of such fuel forms. Therefore, it is imperative to establish models to understand the intrinsic mechanisms and predict the redistribution kinetics.

Phase-Field Simulation for Non-isothermal Solidification of Al-Cu Binary Alloy [PDF]

open access: yesMaterials Research, 2019
Based on the principle of dilute solution approximation, a phase field model for dendritic growth during the non-isothermal solidification process was proposed by coupling the phase field, concentration field and temperature field, and was adopted to ...

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 (

Advanced operator-splitting-based semi-implicit spectral method to solve the binary phase-field crystal equations with variable coefficients [PDF]

open access: yes, 2009
We present an efficient method to solve numerically the equations of dissipative dynamics of the binary phase-field crystal model proposed by Elder et al. [Phys. Rev. B 75, 064107 (2007)] characterized by variable coefficients.

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.

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.
