STRESSES UNDER CIRCULAR LOADED AREAS

A COMPLETE SOLUTION OF THE PROBLEM OF STRESSES UNDER A UNIFORMLY LOADED CIRCULAR AREA AT THE SURFACE OF A SEMI-INFINITE ELASTICALLY ISOTROPIC MATERIAL WAS PUBLISHED BY A.E. LOVE IN 1929 AND BY S.D. CAROTHERS IN 1924. THE GENERAL CONCLUSIONS AND NUMERICAL COMPUTATIONS OF THE TWO INVESTIGATORS ARE IN GOOD AGREEMENT. THE SURFACE OF PARTIAL MAXIMA PRINCIPAL STRESS DIFFERENCES WAS FOUND BY LOVE TO EXTEND DOWN TO A DEPTH OF ABOUT 0.7 OF THE RADIUS OF THE LOADED CIRCLE. THE GREATEST PRINCIPAL STRESS DIFFERENCE IS UNDER THE PERIMETER AT THE SURFACE. CERTAIN APPROXIMATE METHODS OF COMPUTING THE VERTICAL AND SHEARING STRESS ARE DESCRIBED. THE RESULTS ARE SUGGESTED AS A ROUGH GUIDE IN EXPERIMENTATION INVOLVED IN THE STUDY OF THE DESIGN OF FLEXIBLE HIGHWAY SURFACES. /AUTHOR/
