GPFniCS: A generalised phase field method to model fracture

open access: yesSoftwareX, 2023
Advanced damage tolerance design of materials and mechanical components heavily relies on fracture failure analysis. A robust, efficient, and versatile software (GPFniCS) is developed and provided for public access to perform fracture analyses based on ...

Rothe’s Method for Phase Field Problem

open access: yesTrends in Computational and Applied Mathematics, 2007
In this paper, a phase-field model is considered. Analysis of a time discretization for an initial-boundary value problem for this phase-field model is presented. Convergence is proved and existence, uniqueness and regularity results are derived.

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.

Phase-Field Crystal Method for Bilayer Graphene

open access: yesNanomaterials
Bilayer graphene has been a subject of intense study in recent years. Its most common structure is AB (Bernal) stacking, where one layer is shifted relative to the other, leading to distinct electronic behaviors compared to the less stable AA stacking or

Computational thermodynamics and microstructure simulations to understand the role of grain boundary phase in Nd-Fe-B hard magnets

open access: yesScience and Technology of Advanced Materials, 2021
To control the coercivity of Nd hard magnets efficiently, the thermal stability of constituent phases and the microstructure changes observed in hard magnets during thermal processes should be understood.

Sharp Phase Field Method [PDF]

open access: yesPhysical Review Letters, 2018
Phase field modelling offers an extremely general framework to predict microstructural evolutions in complex systems. However, its computational implementation requires a discretisation scheme with a grid spacing small enough to preserve the continuous character of the theory. We present here a new formulation, which is intrinsically discrete, in which

Phase Field Simulation Research on the Microstructural Evolution of Monocrystalline and Polycrystalline Silicon

open access: yesCrystals, 2022
This work simulates the morphological evolution process of the solidification interface of silicon crystal. Based on the phase field model of single dendrite growth of pure material in a single-phase system, the control equation of the phase field is re ...

Application of phase field model coupled with convective effects in binary alloy directional solidification and roll casting processes

open access: yesFrontiers in Materials, 2022
Based on the Kim-Kim-Suzuki (KKS) phase field model coupled with the thermodynamic parameters, the transformation process from columnar dendrites to equiaxed crystals during directional solidification of aluminium alloy was simulated, and the effects of ...

Effect of Shear Flow on Nanoparticles Migration near Liquid Interfaces

open access: yesEntropy, 2021
The effect of shear flow on spherical nanoparticles (NPs) migration near a liquid–liquid interface is studied by numerical simulation. We have implemented a compact model through which we use the diffuse interface method for modeling the two fluids and ...
