Temperatures Field Calculation in an Anisotropic Solid through Finite Elements Method : Tridimensional Case

Application of the finite elements method to the capacitance calculation

The most popular instrumentation used in the Electrical Engineering, presents edges that in the presence of an important electric field, act like as concentrating of electrostatic load and for they turn in the points with major probability of acting as way of an electrostatic discharge. The study from the electrostatic point of view of the behaviour of an edge, presents a singularity, since in ...

Calculation of Matrices of Field Elements . Part

The articles [8], [3], [10], [11], [4], [1], [5], [2], [13], [6], [7], [12], and [9] provide the notation and terminology for this paper. In this paper i denotes a natural number. Let K be a field and let M1, M2 be matrices over K. The functor M1 −M2 yielding a matrix over K is defined by: (Def. 1) M1 − M2 = M1 + −M2. One can prove the following propositions: (1) For every field K and for every...

Calculation of Local Iron Loss in Electrical Machines Using Finite Elements Method

Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...

An Enhanced Finite Element method for Two Dimensional Linear Viscoelasticity using Complex Fourier Elements

In this paper, the finite element analysis of two-dimensional linear viscoelastic problems is performed using quadrilateral complex Fourier elements and, the results are compared with those obtained by quadrilateral classic Lagrange elements. Complex Fourier shape functions contain a shape parameter which is a constant unknown parameter adopted to enhance approximation’s accuracy. Since the iso...
