As the rational finite element interpolates with the soultions of elasticity and formulates directly in the physical domain, it has superiority over the isoparametric finite element in clear physical meaning and accuracy. 由于理性有限元用弹性力学的解插值并且在物理域内直接列式 ,因而与等参元相比 ,...
The Finite Element Method is a technique used to predetermine the vibration characteristics of electric machines by modeling complicated geometries and magnetic materials with ease, allowing for the analysis of air gap magnetic fields, magnetic forces, and noise-producing vibrations. ...
elastic-plastic finite element method 刚度矩阵,进行下一个增量步计算,直到求得整个弹一塑性间题的解。根据采用的刚度矩阵形式,可分为切线刚度法和割线刚度法。 .代法是对变形体施加载荷采用某一近似刚度矩阵求出初步位移解,根据此解计算应力和相应的载荷,并用载荷的差值继续计算附加位移增量,按上述步骤进行叠代,...

P. Silvester - mainly on the Finite-Element Method applied to problems in electrical engineering and as recorded by his writings - is reviewed, with particular reference to the innovations he introduced. A complete bibliography of Silvester's work is appended....
Finite Element Method is used in calculation engine as it is also visible in the name of program (Finite Element Method = FEM). This chapter introduces the main concepts, features and functions of the built-in finite element method.
If you have never used the finite element method implemented in the Wolfram Language, this tutorial is probably not a good starting place. To get an overview of the finite element method, a first reading should be the tutorial Solving Partial Differentia
Compared with the Litz 's or Galegin/s finite-element method in the same no-linear fundament functions, this method has the following advantages: its physical meaning is definite: the part mass balance relationship can be reflected exactly; its calculation formulas are simple and easy to use.Th...
