“…Studies on yielding of sand started from Poorooshasb et al (1966Poorooshasb et al ( , 1967, Scoˆeld and Wroth (1968) and Barden et al (1969) in earnest. Subsequently, Nishi and Esashi (1978) and Vermeer (1978) proposed a model considering yielding behavior accompanied by consolidation, and then Tatsuoka and Molenkamp (1983) discussed about yield surface considering coupling eŠect of consolidation and shear deformation. The yielding characteristic at relatively low stress level was investigated by Ishihara and Okada (1978), Tanimoto and Tanaka (1986) and Tanimoto et al (1987).…”

A series of stress probe tests on Toyoura Sand is fully described in this paper after introducing preliminary works related to (i) the measuring system of the volume change of the specimens, (ii) creep behaviour of sandy specimens and (iii) effect of the slight scattering of initial void ratio of the specimens on the test results obtained from a hollow cylinder apparatus designed for testing sand. The tests results are interpreted based on the concept proposed by Jardine (1985 & 1992) who introduced three yield surfaces representing the boundary of linearly elastic behaviour, nonlinear elastic range and elasto-plastic range. Ten series of stress probe tests in ten different range of stress area in the stress space gives a clear evidence of the isotropic hardening (proportional expansion of yield surfaces) induced by anisotropic repeated loadings.
