摘要
元胞自动机(CA)是复杂体系的一种理想化模型,适合于处理难以用数学公式定量描述的复杂动态物理体系问题,如材料的组织演变等。本文概述了CA法的基本思想及原理,介绍了CA法的基本组成及特征,综述了其在材料介观模拟研究中的应用。研究表明,CA法在金属凝固结晶、再结晶及相变现象等材料介观尺度的组织模拟中表现出特有的优越性。
Cellular Automata (CA) are the ideal models for complex systems, and are very suitable for simulating complex dynamic problems which are hardly described by mathematical formulae, such as evolution of microstructures in materials, etc. The fundamental ideas and theory of the CA were summarized in this paper. The structure and characteristics of the CA were introduced and the applications of Cellular Automata in mesoscopic simulation were reviewed. Some researches show that Cellular Automata possess some especial advantages in simulating mesoscopic behavior such as solidification, recrystallization, phase transformation, etc.
