Plasticity problems, involving non-linear material behaviour, were modelled at this time Gallagher et al. Zienkiewicz suggested that a more appropriate generic name would be the generalized Galerkin method Fletcher 6 The Finite Element Method Once it was realized that the method could be interpreted in terms of variational methods, the mathematicians and engineers were brought together and many extensions of the method to new areas soon followed.
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.
Let us return to the early days of the developments: The text by Hall is particularly useful to those for whom boundary elements are a completely new idea. Zienkiewicz performed stress analysis calculations for human femur transplants. The method is discussed in detail in zieenkiewicz book by Synge However, Black— Scholes models Wilmott et al. 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.
We mention here just two of them. As far as this historical introduction elemenfos concerned, this is where we shall leave the contributions from the engineering community. Enviado por Henrique flag Denunciar.

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 Mesh generation and adaption is an area in which much work is still needed; for a recent account, see Zienkiewicz et al. Thus the period from its conception in the early s to the late s saw the method being applied extensively by the engineering community.
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. 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.
In each of these categories there are equations which model certain physical phenomena.
Stability analysis also comes into this category and was discussed by Martin The immediate advantage is in the reduction of the dimension of the problem. For further details of background and history, see the following: 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 Besides the static analysis described above, dynamic problems were also being tackled, and Archer introduced the concept of the consistent mass matrix.
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 Both vibration problems Zienkiewicz et al.

In general, elliptic equations are associated with steady-state phenomena and require a knowledge of values of the unknown function, or its derivative, on the boundary of the region of interest. Similarly, transient heat conduction problems were considered by Wilson and Nickell In this chapter, we shall consider functions which depend on two indepen- dent variables only, finihos that the resulting algebra does not obscure the underlying ideas.

Finally, parabolic equations model problems in which the quantity of interest varies slowly in comparison with the random motions which produce these. 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.
Similar papers followed by Polya and Weinberger These techniques have been the basis of the formulation of potential elemntos and elasticity by, amongst others, Fredholm and Kellog There are excellent accounts of applications from the mid s onwards in the texts by Zienkiewicz and Taylor a,b.
This is a pure boundary-value problem. 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.
