结果表明，渐近的力学行为(即以恒定变形速率渐近获得的应力)决定了土壤等散体材料的整体力学行为。本文从理性力学的角度出发，导出了砂土的本构模型，或者更确切地说，是一种新的理论框架。这一新的理论被称为“正压”，具有突出的简单性，包含了以前介绍的土力学的概念：临界状态和正压(即刚度对应力的幂定律依赖)。版权所有©2011 John Wiley&Sons，Ltd.
It is shown that the asymptotic mechanical behaviour (i.e. stresses asymptotically obtained with constant deformation rates) determines the entire mechanical behaviour of granular materials, such as soil. In this paper, a constitutive model, or rather a new theoretical framework, for sand is derived in terms of rational mechanics. The new theory, called ‘barodesy’, has an outstanding simplicity and comprises previously introduced concepts of Soil Mechanics: critical states and barotropy (i.e. power law dependence of stiffness on stress).
