Some notes on the use of a constitutive law for sands

Abstract

A minimum dry density function is interpolated in the function of the grading curve on the grading entropy diagram on the basis of data measured by Lőrincz. The function can be extended onto the inverse image of the entropy diagram point. To illustrate the usefulness of the chart it is shown that it can be used for estimating the suction of sands from the grading curve on condition that the relative density and the degree of saturation is known.
