A GRAPHICAL TECHNIQUE FOR DETERMINING THE ELASTIC MODULI OF A TWO LAYERED STRUCTURE FROM MEASURED SURFACE DEFLECTIONS

A THEORETICALLY DERIVED CHART HAS BEEN DEVELOPED BY MEANS OF WHICH THE ELASTIC MODULUS OF EACH LAYER OF A TWO-LAYER ELASTIC STRUCTURE CAN BE EVALUATED. THE REQUIRED INPUT DATA COMPRISES TWO OR MORE SURFACE DEFLECTIONS OBSERVED AT DIFFERENT KNOWN DISTANCES FROM A KNOWN VERTICAL LOAD, TOGETHER WITH KNOWLEDGE OR AN ESTIMATE OF THE THICKNESS OF THE UPPER LAYER. THE LOWER LAYER IS ASSUMED TO BE OF INFINITE THICKNESS. ONE VERSION OF THE CHART AND DIRECTIONS FOR ITS USE ARE PRESENTED. /AUTHOR/
