Simulation of size effects by a phase field model for fracture

Theoretical and Applied Mechanics Letters, 2014
In phase field fracture models the value of the order parameter distinguishes between broken and undamaged material. At crack faces the order parameter interpolates smoothly between these two states of the material, which can be regarded as phases.

Phase Field Study of Microstructure Evolution in Eutectoid Phase Transformation – I Nucleation

Archives of Foundry Engineering, 2017
Eutectoid growth, as the important reaction mechanism of the carbon steel heat treatment, is the basis to control the microstructure and performance. At present, most studies have focused on lamellar growth, and did not consider the nucleation process ...

Parameters affecting microsegregation in phase-field simulation

Transactions of Nonferrous Metals Society of China, 2006
The influence of various material and computational parameters such as interface kinetic coefficient(β), surface energy(σ), anisotropy parameter(γ) and the noise amplitude(α) upon microsegregation patterns during the crystal growth was investigated by using the phase-field model which incorporated the concentration field equations. The computed results
