Phase-field 方法的基本思路-特点42在晶粒生长中的应用从获得的文献来看近年来计算机模拟晶粒长大的方法和思路越来越多其中最引人关注的是以相场模型描述晶粒长大过程这种模型的特点是将晶界作弥散化处理不必直接跟踪复杂的动态界面演化过程易于将物理场与晶界几何形态等复杂因素对晶粒长大过程的影响考虑进来物理意义更加...
The phase-field method is a powerful simulation tool to describe xxx the complex evolution of interfaces in a wide range of contexts without explicitly tracking these interfaces. Its main application to date has been to problems in materials science where the evolution of interfaces and defects in...

The phase-field method has recently emerged as a powerful computational approach to modeling and predicting mesoscale morphological and microstructure evolution in materials. It describes a microstructure using a set of conserved and nonconserved field variables that are continuous across the interfacial reg...
The phase-field does not describe the crack as a physical discontinuity and just smoothly transits the intact material to the thoroughly broken one. The shape and propagation of the crack depend on the evolution equations of the phase-field. Thus, implementation of the phase-field does not ...
Phase-field models have become popular in recent years to describe a host of free-boundary problems in various areas of re- search. The key point of the phase-field approach is that surfaces and interfaces are implicitly described by continuous scalar fields that take constant values in the bul...
A phase-field model for a general class of multi-phase metallic alloys is now proposed which describes both multi-phase solidification phenomena as well as polycrystalline grain structures. The model serves as a computational method to simulate the motion and kinetics of multiple phase boundaries and...
相场方法是20世纪90年代中期发展的一种扩散界面方法,它是以Ginzburg-Landau理论为物理基础,通过微分方程来体现具有特定物理机制的扩散、有序化势和热力学驱动的综合作用,通过计算机编程求解上述方程,从而获取研究体系在时间和空间上的瞬时状态。与VOF、LS和FT方法具有锐利界面的特性不同,相场方法的界面存在一定厚度,密度、...
