Abstract

A mixed formulation for the three-dimensional analysis of steady heat-conduction problems is presented. The method developed permits prescription of the boundary conditions in terms of either the temperature or the heat flux, or a combination of both. The general expressions for the temperature and the heat fluxes are derived in the form of a series in powers of the linear partial differential operators which operate on a set of initial functions to be determined by the prescribed boundary conditions. One of the important features of this method is its ability in providing approximate solutions in closed form. In order to illustrate the procedure some representative example problems with respect to thick plates have been solved, the corresponding solutions leading to results of engineering accuracy
