Stress probe tests were conducted on the Toyoura sand by several complicated stress paths to determine the yield function of the sand in a loose state. Main conclusions derived were as follows : a) The characteristics of yield locus of the sand was found to be dq/dp′=F(η) independent of the stress path experienced by the sample. b) The yield loci could be represented by a single curve in (p^*, q^*) space, where p^*=p′/p_e, q^*=q/p_e, and p_e is a newly defined parameter. c) The dimensionless yield curve in (p^*, q^*) space was represented by a combined curve of ellipse and parabola. d) Based on the state path depicted on (p^*, q^*) space, the stress &acd
