Abstract:

This document describes research work necessary to fullfill the requirements of the contract that must lead to the establishment of a computer program able to calculate all stressed and displacements in a four layered system with fixed bottom submitted to a series of loads. This report contains three parts 1 A complete discussion of the interface conditions 2 The demonstration that satisfying convergency can be obtained, and in the meantime overflow problems can be eliminated, if the equations are written in closeform although in a sufficient comprehensive form so that the whole problem can still be overlooked but in such a way that all numerical problems can be solved and 3 The complete algebraical analysis leading to the equations in extended form for an isotropic four-layered system. The analysis is also developed for a three-layered system to enable us to compare and to check the results with those obtained by means of reliable existing programs.
