System Properties

The finite element method of lubrication analysis is presented for the novice from a viewpoint closely analogous to that of the familiar direct stiffness method of structural analysis. The lubricant film is seen as a system of component elements interconnected at nodal points where flows are summed and pressures (but not necessarily thicknesses, viscosities, or densities) are equated. System properties are deduced from component properties and connections. Detailed equations needed for solution of practical problems are given in Appendices and their use is illustrated in Examples.

Abstract This text sums up a research for the French Electric Company, EDF, which wants to know the influence of the temperature variability on the reliability of some of their boilers. These boilers are very complex structures whose behavior has to be modelized by the Finite Element Method, FEM. This work is an application of Finite Element Methods in a reliability context, that means the introduction of random data into a classical FEM, in order to determine the reliability of the structures. These random data may concern geometry, material characteristics of the structures or the loads the structure may carry. Then, it’s necessary to employ new methods to take into account these stochastic approaches and to obtain more efficient decision’s elements for a better control of the boilers.

Preliminary Research

For a structural analysis using the finite element method, a hexahedral element is preferable to a tetrahedral element from the viewpoint of accuracy. However, it is very difficult to subdivide a mesh consisting of hexahedral elements if the shape of the mesh is complicated. Hence, in this paper, as a preliminary research, we use a label-driven subdivision method for a two-dimensional mesh, and show that meshes subdivided nonuniformly can guarantee as much accuracy as meshes with uniform subdivision.
