Undrained Failure Criteria for Isotropic and Anisotropic Soils

Abstract

A new total stress failure criterion applicable to both isotropic and anisotropic soils under undrained conditions is proposed. The new criterion, which is motivated by elastic anisotropy in the underlying effective stress-strain behavior, is shown to be consistent with reported data for undrained shear strengths obtained in triaxial compression, triaxial extension, and direct simple shear tests.
