Abstract In this chapter, we present the method of finite elements which is the numerical method of choice for the calculation of solutions of elliptic boundary value problems, but is also used for parabolic or hyperbolic problems as we shall see.

The finite-difference approach with equidistant grids is easy to understand and straightforward to implement. The resulting uniform rectangular grids are comfortable, but in many applications not flexible enough. Steep gradients of the solution require a finer grid such that the difference quotients provide good approximations of the differentials.

The approximate methods presented at the end of the preceding chapter for the solution of the vibration problems of continuous systems are based on the assumption that the shape of the deformation of the continuous system can be described by a set of assumed functions. By using this approach, the vibration of the continuous system which has an infinite

In this chapter, we first introduce the differences between the finite element method (FEM) and the previously introduced FDM and FVM. Then, the focus will be placed on the Galerkin method for obtaining the weak form of the governing equation. Using thermomechanics as an example, the discretization of the weak form of the governing equations with ...

Finite element methods (FEM) were used very early for problems in structural mechanics. Such problems often have a natural discretization by partitioning the structure in a number of finite elements, and this gave the name to this class of methods. This kind of mechanical approach merged with the more mathematical approach that gained momentum in the ...

Wir haben die Methode der finiten Elemente schon in Kapitel 3.7 zum Losen gewohnlicher Randwertprobleme eingefuhrt und angewandt. Das eigentliche Anwendungsgebiet sind jedoch die partiellen Differenzialgleichungen und vorzugsweise die elliptischen Randwertprobleme.

The finite element method is used here to validate the analytical–numerical method presented in Chap. 3. The basic assumption and the used equations for thin plates in both the methods (ANM—the analytical–numerical method, FEM—the finite element method) are identical, but the way of solution is different.

The Finite Element Method (FEM) was originated from the field of structural calculation (e. g. stress analysis) in the beginning of the fifties. The terminus -finite elements — was introduced by Turner et al. (1956). The concept of the finite element technique consists in a subdivision of a complex structure into small substructures assembling the ...
