In this chapter, we shall consider functions which depend on two indepen- dent variables only, so that the resulting algebra does not obscure the underlying ideas.

Courant gave a solution to the torsion problem, using piecewise linear approximations over a triangular mesh, formulating the problem from the principle of minimum potential energy. There are excellent accounts of applications from the mid s onwards in the texts by Zienkiewicz and Taylor a,b. The text by Hall is particularly useful to those for whom boundary elements are a completely new mwtodo.

It was with developments in computing and numerical procedures that the technique became attractive to physicists and engineers in the s Hess and Smithand the ideas developed at that time were collected together in a single text Jaswon and Symm In order that the solution is unique, it is necessary to know the potential or charge distribution on the surrounding boundary.

Finally, parabolic equations model problems in which the quantity of interest varies slowly in comparison with the random motions which produce these. Similar papers followed by Dee and Dee We mention here finiyos two of them. Recently, further developments in so-called mesh-free methods have been proposed Goldberg and ChenLiu ; included is the method of fundamental solutions Goldberg and Chenwhich has its origins in the work on potential problems by Kupradze In such problems it is usually required to know the displacement, or its derivative, at the ends, together with the initial displacement and velocity distribution.

Enviado por Henrique flag Denunciar. The workers in the early s soon turned their attention towards the solution of non-linear problems. The immediate advantage is in the reduction of the dimension of the problem. Let us return to the early days of the developments: These techniques have been the basis of the formulation of potential theory and elasticity by, amongst others, Fredholm and Kellog The reader interested in becoming familiar with current mathematical approaches to the method should consult Brenner and Scott or the very readable text by Axelsson and Barker This is a pure boundary-value problem.

Indeed, it will always be an equation together 8 The Finite Element Method with prescribed conditions which forms a mathematical model of a particular situation. elemejtos

Zienkiewicz suggested that a more appropriate generic name would be the generalized Galerkin method Fletcher 6 The Finite Element Method The principles could be clearly seen in the much earlier work of Lord Rayleigh Strutt and Ritz This is an initial boundary- value problem.

Besides the static analysis described above, dynamic problems were also being tackled, and Archer introduced the concept of the consistent mass matrix. Zienkiewicz performed stress analysis calculations for human femur transplants.

The mathematical basis of the method then started in earnest, and it is well beyond the scope of this text to do more than indicate where the interested reader may wish to start. Zienkiewicz, Kelly et al.

Similarly, transient heat conduction problems were considered by Wilson and Nickell Thus the period from its conception in the early s to the late s saw the method being applied fl by the engineering community.

A three-dimensional problem in electrostatics was solved, using linear tetrahedral elements, by McMahon However, Black— Scholes models Wilmott et al.

Mesh generation and adaption flementos an area in which much work is still needed; for a recent account, see Zienkiewicz et al. The method is mefodo in detail in the book by Synge Both vibration problems Zienkiewicz et al. A very good overview of the early development of boundary elements was given by Becker From a physical point of view, it meant that problems outside the structural area could be solved using standard structural packages by associating suitable meanings to the terms in the corresponding variational principles.

As far as this historical introduction is concerned, this is where we shall leave the contributions from the engineering community. Zienkiewicz noted that Courant had already developed some of the ideas in the s without zienkiewkcz them further. Enviado por Henrique flag Denunciar. Plasticity problems, involving non-linear material behaviour, were modelled at this time Gallagher et al.

Once it was realized that the method could be interpreted in terms of variational methods, the zienkiewic and engineers were brought together and many extensions of the method to new areas soon followed.

Stability analysis also comes into this category and was discussed by Martin In general, elliptic equations are associated with steady-state phenomena and require a knowledge of values of the unknown function, or its derivative, on zirnkiewicz boundary of the region of interest. For further details of background and history, see the following: In each of ziehkiewicz categories there are equations which model certain physical phenomena.

For a general guide to current research from both an engineering and a mathematical perspective, the reader is referred to the sets of conference proceedings MAFELAP From toedited by Whiteman, and BEM From toedited by Brebbia. Finally, the two-volume set by Aliabadi and Wrobel zienkiewjcz a similar state-of-the-art work on boundary elements, as does the three-volume set by Zienkiewicz and Taylor a,b and Zienkiewicz et al.
