Modeling of inter- and transgranular stress corrosion crack propagation in polycrystalline material by using phase field method

Journal of the Mechanical Behavior of Materials, 2017
A coupled multiphysics phase field framework is proposed to model anodic dissolution induced by stress corrosion fracture growth at microstructual level.

Electric Field Induced Collapse of Charge-Ordered Phase in Manganites [PDF]

, 2006
The colossal electroresistance in manganites is a concomitant of the electric field induced insulator-to-metal phase transition. A phenomenological phase transition model is proposed to study this electric field induced collapse of charge-ordered phase ...

Influence of wall roughness on two-phase displacement

Shenzhen Daxue xuebao. Ligong ban, 2022
In the development of oil and gas fields, water flooding is still the most important development method. The influence of the existence of rough channel on two-phase flow cannot be ignored.

Multi-Phase-Field Model for Surface/Phase-Boundary Diffusion

, 2017
The multi-phase-field approach is generalized to treat capillarity-driven diffusion parallel to the surfaces and phase-boundaries, i.e. the boundaries between a condensed phase and its vapor and the boundaries between two or multiple condensed phases ...

Permeability Measurements of 3D Microstructures Generated by Phase Field Simulation of the Solidification of an Al-Si Alloy during Chill Casting

Metals, 2021
The permeability of the semi-solid state is important for the compensation of volume shrinkage during solidification, since insufficient melt feeding can cause casting defects such as hot cracks or pores.

Complex order-parameter phase-field models derived from structural phase-field-crystal models

, 2013
The phase-field-crystal (PFC) modeling paradigm is rapidly emerging as the model of choice when investigating materials phenomena with atomistic scale effects over diffusive time scales.

An enhanced phase field model for micron-scale droplet impact with solidification microstructure formation

Materials Research Express, 2021
In this work, a novel diffuse interface model combining droplet impact with solidification microstructure formation was developed. A number of numerical models simulating droplet impact with solidification have been invented, but few are capable of ...

Phase-field approach to heterogeneous nucleation

, 2002
We consider the problem of heterogeneous nucleation and growth. The system is described by a phase field model in which the temperature is included through thermal noise.
