VISCOELASTIC ANALYSIS OF THREE-LAYER SYSTEMS

THIS REPORT PRESENTS AN ANALYSIS OF THE SURFACE DEFLECTION OF A THREE-LAYERED SYSTEM UNDER A UNIFORMLY DISTRIBUTED NORMAL CIRCULAR LOAD. EACH LAYER OF THE SYSTEM IS ASSUMED TO BE COMPOSED OF MATERIALS WHICH BEHAVE LINEAR VISCOELASTICALLY. THE SOLUTION TO THE PROBLEM IS OBTAINED BY USING A CORRESPONDENCE PRINCIPLE IN CONJUNCTION WITH THE KNOWN ELASTIC LAYERED SYSTEM SOLUTION. THIS SOLUTION IS IN THE FORM OF AN INTEGRO-DIFFERENTIAL EQUATION INVOLVING MULTIPLE CONVOLUTION INTEGRALS. NUMERICAL TECHNIQUES FOR SOLVING THIS EQUATION ARE PRESENTED. RESULTS OBTAINED USING THE NUMERICAL TECHNIQUES ON THE INTEGRO-DIFFERENTIAL EQUATION ARE PRESENTED AND DISCUSSED. FOR THE PARTICULAR MATERIAL CHARACTERIZATION USED IN THIS STUDY, THE RESULTS OF THE ANALYSIS HAVE SHOWN THE POSSIBILITY OF DEFINING A RETARDATION TIME FOR THE LAYERED SYSTEMS. THE EFFECT OF GEOMETRICAL AND MATERIAL PROPERTIES ON THIS RETARDATION TIME INVITES THE POSSIBILITY OF ITS USE FOR THE STUDY OF EQUIVALENCY FACTORS OF VARIOUS PAVING MATERIALS. /AUTHOR/
