Several similarities are observed between stress-strain characteristics of a sand at high pressures and those of a normally consolidated clay at ordinary pressures. From this an indication is given that the stress-strain responce of a sand at high stresses may be predicted by using the equations which have been proposed by Roscoe et al. for normally consolidated clays. In the previous paper, it was shown that the stress-strain behavior of the Toyoura standard sand in a dense state can approximately be predicted by using the Cam-clay equation or the revised equation. In this paper, the discussions are extended to the prediction of the stress-strain responce of the Toyoura standard sand in a loose state. Some experimetal results on the Ube kaolin are also presented to show the close resemblance between behaviors of a sand and clay at different stress levels.
