Multigrain phase-field simulation in ferroelectrics with phase coexistences: An improved phase-field model

Computational Materials Science, 2022
A new 3D phase-field model is developed to investigate the evolution of the domain structure and phase transformation in a ferroelectric material near the morphotropic phase boundary (MPB) under the influence of external stimuli. The model combines the Landau–Ginzburg–Devonshire (LGD) theory with a general multiphase approach and enables to ...

Phase field simulations of ferroelectric materials

2014
Ferroelectric materials have become preferred materials in a wide variety of electronic and mechatronic devices due to their pronounced dielectric, piezoelectric, and pyroelectric properties. The material macroscopic properties are related to the microscopic domain structure of the materials.

Isogeometric Phase-Field Simulation of Boiling

2016
In this work we consider the Navier–Stokes–Korteweg equations, a diffuse-interface model describing liquid–vapor phase transitions. A numerical scheme for this model is constructed based on functional entropy variables and a new time integration concept.

Phase-field-crystal simulation of nonequilibrium crystal growth

Physical Review E, 2014
By using the phase field crystal model, we simulate the morphological transition of the crystal growth of equilibrium crystal shape, dendrite, and spherical crystal shape. The relationship among growth morphology, velocity, and density distribution is investigated.

A Scalable Implicit Solver for Phase Field Crystal Simulations

2013 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum, 2013
The phase field crystal equation (PFC) is a popular model for simulating micro-structures in materials science and is very computationally expensive to solve. A highly scalable solver for PFC modeling is presented in this paper. The equation is discredited with a stabilized implicit finite difference method and the time step size is adaptively ...

Extreme Scale Phase-Field Simulation of Sintering Processes

2019 IEEE/ACM 10th Workshop on Latest Advances in Scalable Algorithms for Large-Scale Systems (ScalA), 2019
The sintering process, which turns loose powders into dense materials, is naturally found in the formation of glaciers, but is also the indispensable process to manufacture ceramic materials. The dynamically evolving microstructure, which is established during this process, largely influences the resulting material properties.

Phase-field simulations of partial melts in geological materials

Computers & Geosciences, 2009
A diffuse interface description based on a multi-phase-field model for geological grain microstructures is introduced, especially useful in the treatment of partially molten structures. Each grain as well as different phases are represented by individual non-conserved order parameters, the phase fields @f"@a, which are defined on the complete ...
