LAYERED SYSTEMS UNDER NORMAL SURFACE LOADS

USING A MATRIX FORMULATION THE AUTHORS HAVE EXTENDED A TECHNIQUE FIRST FORMULATED BY THOMSON WHICH GREATLY SIMPLIFIES THE PROBLEM OF DETERMINING THE DISTRIBUTION OF STRESS IN A STRATIFIED SEMI-INFINITE ELASTIC MEDIUM UNDER THE COMPRESSIVE ACTION OF A RIGID BODY. THIS PROBLEM, FIRST PRESENTED FOR AN UNSTRATIFIED MEDIUM BY BOUSSINESQ AND GENERALIZED TO LAYERED SYSTEMS BY BURMISTER, BECOMES EXTREMELY CUMBERSOME ALGEBRAICALLY WHEN MORE THAN ONE LAYER RESTING ON A SEMI-INFINITE ELASTIC SOLID IS CONSIDERED. THE SIMPLIFICATION PROPOSED IN THE PAPER PROVIDES A READY SOLUTION OF THE BOUNDARY CONDITION PROBLEM. A COMPUTER PROGRAM IN FORTRAN IV (IBM 7094) HAS BEEN WRITTEN FOR THE NUMERICAL CALCULATION OF STRESSES, STRAINS AND DISPLACEMENTS AT ANY POINT IN AN IDEALLY ELASTIC MULTILAYER ROAD SYSTEM, INDUCED BY ONE OR MORE VERTICAL AXISYMMETRIC SURFACE LOADS UNIFORMLY DISTRIBUTED OVER CIRCULAR AREAS. THE CALCULATION OF THE STRESS DISTRIBUTION WITH THIS PROGRAM HAS PROVED TO BE EFFECTIVE AND ACCURATE, IRRESPECTIVE OF THE NUMBER OF LAYERS. /AUTHOR/
