This study shows that it is not possible to characterize the behavior of the sand accurately by a single value of Poisson's ratio.Moreover,because the sand dilates under the action of shear stresses,the most appropriate stress-strain relationship would reflect the influence of shear stresses on volume changes.For the purposes of the studies described herein,however,it has been assumed that the soil may be characterized by a single constant value of Poisson’s ratio,and no effort has been made to relate volume changes to shear stresses .The values of Poisson's ratio used in subsequent calculations were selected to represent,in a general way,the values of confining pressure and stress levels involved in the stress conditions analyzed.
