Popis:	Frictional interaction between granular materials and solid surfaces is encountered in many geotechnical applications. Such an interaction develops through a very thin layer of soil called interface. This paper deals with the formulation of a nonassociated elastoplastic model for interface behaviour under monotonic and cyclic conditions. Two plastic surfaces are employed: an external surface subjected to isotropic hardening and an internal one subjected to a purely kinematic rotational hardening. Flow rule is similar to that used in Cam Clay model but differs if hardening or softening conditions are involved. 2003 Elsevier Science Ltd. All rights reserved.
