摘要：

This paper presents a phenomenological continuum model describing no-tension effects observed in granular materials. Constitutive laws are derived from a strain-energy function, which must vanish in the positive stress directions. Computational aspects are then investigated, wherein the finite element formulation is developed in the principal deformation directions. Last, a numerical example of a ballast structure will be outlined for illustrative purposes. (C) 2003 Elsevier Ltd. All rights reserved.
