有限元分析(finite element analysis,FEA)是用有限元法把一个物体或系统分解为由多个相互联结的、简单的、独立的有限数量点组成的几何模型,通过分析每个单元的性质,来获得整个物体性质的一种分析方法。一、三维有限元在口腔正畸领域的应用有限元法于1956年最先应用在航空工业,1973年Theresher[1]和Farah首次将有限元法用于口腔领域。1980年日本学者Takahashi[2]对在不同的加载条
Finite element analysis (finite element analysis, FEA) is the finite element method to decompose an object or system into several geometric models consisting of many interconnected, simple and independent finite number of points. By analyzing the properties of each element, To get the nature of the entire object of an analytical method. First, the application of three-dimensional finite element in the field of orthodontics Finite element method was first applied to the aviation industry in 1956, in 1973 Theresher [1] and Farah for the first time the finite element method for the oral area. In 1980, Japanese scholar Takahashi [2] wrote about the different loading bars
