摘要/Abstract

摘要： 以能量守恒原理为主线，在各向同性前提下，对Taylor剪胀方程、Camclay剪胀方程、修正Camclay剪胀方程、Rowe剪胀方程和扩展的Rowe剪胀方程等进行了较全面的综述.论证了剪胀方程和塑性势函数之间的相互转化关系.指出了LadeKim塑性势函数和Nova塑性势函数的缺陷之处，即这两个塑性势函数均没有合理耦合临界状态这一概念.

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
