在相场法中,通过修改控制方程,界面保持相对清晰。假设界面具有有限厚度,并由热力学一致守恒定律描述。然而,在实际实现中,过渡区的厚度比实际系统中的厚度大得多,并且我们不清楚在保持热力学条件而产生的人工…

The method is particularly appealing because it provides a visual impression of the development of structure, one which often matches observations. The essence of the technique is that phases and the interfaces between the phases are all incorporated into a grand functional for the free energy of ...
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...

Rechargeable batteries have a profound impact on our daily life so that it is urgent to capture the physical and chemical fundamentals affecting the operation and lifetime. The phase-field method is a powerful computational approach to describe and predi
Several computational examples are given to illustrate the power of the method to simulate realistic microstructures and to obtain quantitative results. The last section briefly discusses phase field models for other applications.DOI: 10.1016/B0-08-043152-6/01219-5 年份: 2001 ...
The thermodynamic extremal principle (TEP) formulated in discrete parameters [1] represents a handy tool in modeling of thermodynamic processes in solids. As a further concept the phase field method (PFM) has gotten an established method for simulation of microstructure evolution and allows accounting...
In the present work, we study the phenomenon of grain-boundary grooving under electromigration using a phase-field method. The specific focus of the work is to explore the role of grain boundaries as potential electromigration pathways. We consider the evolution of grooves under the combined influen...
