Computer Programs for the Determination of Stresses and Displacements in Four Layered Systems with Fixed Bottom.
Abstract
This report deals with the mathematical aspects required for the establishment of a computer program able to calculate all stresses and displacements in a four layered system. The materials of the different layers may be isotropic or coross anisotropic. The interface conditions cover all the cases from full friction to full slip included partial friction. The bottom of the fourth layer is considered to be fixed (no vertical deflections). The report is based on (1) previous research on isotropic multilayer theory and (2) original research on interface conditions (fixed bottom, partial friction) and satisfactory convergency, thus complete accuracy, at the surface and in the first layer of the system. This rport contains (1) a theoretical outline wherein the basic equations are given, the specific boundary conditions discussed and the particular numerical problems related to the accuracy at the surface and in the first layer are solved. (2) the general mathematical analysis of the chosen numerical solution and a description of the programs and their utilization. and (3) appendices) the detailed mathematical and algebrical analyses for the different considered cases. The programs are written in FORTRAN 77 and run on IBM PC or other compatible equipment. Keywords: Pavement design.
