摘要

The paper analyses the conditions for a developing localization zone in a porous solid (soil) subjected to undrained conditions, while the solid skeleton is assumed to undergo finite elastic-plastic deformation. A basic feature of the analysis is the concept of a regularized displacement discontinuity (and the consequent pore pressure discontinuity) which was recently adopted by Larsson et al. (1996) in the context of geometrically linear theory. The geometric effect due to elastic compressive strains is investigated in a numerical example of biaxial loading under the plane strain conditions. The findings might have relevance for the interpretation of phenomena involving soft and weak geomaterials. (C) 1998 Elsevier Science Ltd. All rights reserved. [References: 19]
