Abstract: Along a clue of the energy conservation, different type dilatancy equations of homogeneity sands, such as Taylors, Camclays, modified Camclays, Rowes and expanded Rowes et al. are reviewed and commented systematically, and transferring formulations between the dilatancy equations and their plastic potentials are given in detail. At last, it is pointed out that the obvious shortcoming of LadeKim and Nova plastic potential functions, which is that the two potential functions are not reasonably incorporated in the concept of critical state.

Key words: homogeneity; dilatancy equation; plastic potential; yield potential; nonassociated flowing rule
