Phase-field modeling of frost propagation of cracks for rock mass under frost action
Yantu 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
MRS 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]
IMA 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 FeMn system
Journal of Materials Research and Technology, 2016 The present investigation shows quantitative results for the peritectic phase transformation of FeMn 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
Mathematics, 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.

Phase field methods and dislocations [PDF]
Acta 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.
