INFLUENCE OF POISSON'S RATIO ON THE SURFACE DEFLECTION OF LAYERED SYSTEMS

THREE DIFFERENT THEORIES ARE USED TO EVALUATE THE INFLUENCE OF VARIATIONS IN POISSON'S RATIO ON THE SURFACE DEFLECTION FUNCTION FOR TWO-LAYERED ELASTIC SYSTEMS. THESE THEORIES ARE SHOWN TO BE QUALITATUVELY INCONSISTENT IN ACCOUNTING FOR THIS EFFECT, WHICH MAY AMOUNT TO 25 PERCENT OF MORE FOR CERTAIN COMBINATIONS OF VALUES, AND THEY OFTEN YIELD DEFLECTION FACTORS THAT DIFFER FROM ONE ANOTHER BY OVER 100 PERCENT FOR SIMILAR CONDITIONS. THE PRACTICAL APPLICABILITY OF THE THEORIES IS APPRAISED BY COMPARING THEORETICAL RESULTS WITH THOSE OBTAINED FROM A LIMITED EXPERIMENTAL STUDY; THIS COMPARISON IS MOST FAVORABLE FOR THE EQUIVALENT THICKNESS THEORY. /AUTHOR/
