Simulation of Dendritic-Eutectic Growth with the Phase-Field Method

Acta Materialia, 2023
Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys is usually made up of dendrites, eutectics or a combination of both. The evolving morphologies are largely determined by the solidification process and thus many materials properties are dependent on the processing conditions.

Study on Dynamic Behavior of Disperse Phase Water Droplets in Non-uniform Electric Field

Shiyou jixie, 2018
To study the dynamic behavior and influencing factors of disperse phase water droplets in a non-uniform electric field formed by tubular electrodes, a physical model of water droplets in a non-uniform electric field is established using phase-field ...

A modified damage and fracture phase field model considering heterogeneity for rock‐like materials

Deep Underground Science and Engineering, 2023
Damage and fracture are the most extensive failure modes of rock materials, which may easily induce disaster and instability of engineering structures.

Phase transitions and spin excitations of spin-1 bosons in optical lattice

, 2017
We investigate ground state properties of spin-1 bosonic system trapped in optical lattice with extended standard basis operator (SBO) method. For both ferromagnetic ($U_20$) systems, we analytically figure out the symmetry properties in Mott-insulator ...

Thermodynamic properties and phase diagrams of spin-1 quantum Ising systems with three-spin interactions

, 2011
The spin-1 quantum Ising systems with three-spin interactions on two-dimensional triangular lattices are studied by mean-field method. The thermal variations of order parameters and phase diagrams are investigated in detail.

Phase-field modeling of thermo-mechanical coupled brittle fracture for transversely isotropic rock

Yantu gongcheng xuebao
Thermally induced deformation and fracture of bedding rocks are critical concerns in geotechnical engineering, including geothermal mining and nuclear waste storage, as these phenomena are strongly influenced by material anisotropy.
