The Finite Element Method [PDF]
, 1991 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 the principles of the finite element method will be presented through the application to problems of steady and nonsteady groundwater flow. The method was developed in the 1950’s, first for problems of aeronautical engineering (the construction of airplanes), mechanical engineering (nuclear reactor vessels), and civil engineering ...

Finite element method (FEM) is widely used in various engineering fields to solve problems with too many complexities to be dealt with by certain conventional approaches. In 1943, Courant proposed the theoretical basis of the method, and, in 1956, Turner et al.

The Finite Element Method (FEM) is a numerical technique used to solve partial differential equations by transforming them into a matrix equation. The primary feature of FEM is its ability to describe the geometry or the media of the problem being analyzed with great flexibility.

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.

A Multiscale Finite-Element-Method
Civil-Comp Proceedings, 1997Abstract This paper describes a hierarchical overlay of a p -version finite element approximation on a coarse mesh and an h -approximation on a geometrically independent fine mesh. The length scales of the local problem may be some orders of magnitude below the scale of the global problem.

Die analytischen Rechenansatze in den vorangegangenen Abschnitten dieses Buches dienten dem Zweck, das Verstandnis fur die grundlegenden Beziehungen zwischen Kraftwirkungen und Verformungen zu entwickeln. Umfang und Schwierigkeitsgrad der in der Praxis auftretenden Probleme ubersteigen allerdings schnell die Reichweite dieser Rechenansatze.

Continuous elements in the finite element method [PDF]
International Journal for Numerical Methods in Engineering, 1978 AbstractThe discretization of the media at all spatial co‐ordinates but one is presented here. This partial discretization leads to continuous finite elements as opposed to fully discrete ones and the problem resolves, for the cases presented here, into a set of linear differential equations rather than algebraic equations. The general problem of first

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.
