In addition to the basic FEM heat transfer concepts and implementation, we have also presented some modem techniques which are being used to enhance the accuracy and speed of the conventional method.

With the increased use of fiber-reinforced composites in structural components, studies involving the behavior of components made of composites are receiving considerable attention. Functional requirements and economic considerations of desi

When analyzing the cross section of machines we saw that by taking advantage of the periodic nature of the field in some machines, we could, by using periodic or anti-periodic boundary conditions, reduce the size of the problem and solve for one or two pole pitches instead of the entire cr

Siegmar-W. Breckle,M. Daud Rafiqpoore mechanics may be presented. On a macroscopic level the complete mechanical behaviour of structural components can be described with such nonmonotone and possibly multivalued relations. A typical example of this kind is the delamination process of a composite structure, where local delaminations, c

In recent times (1960), the FEM has been studied by applied mathematicians and, having received rigorous treatment, has become a part of the more general study of partial differential equations, gradually replacing the finite difference method which had been cons

In this context, numerical stability means that round-off errors introduced at each step of the integration process tend to decay out. As a consequence, solution a
