Abstract
Frictional interaction between granular materials and solid surfaces is encounteredin many geotechnical applications. Such an interaction develops through a very thin layer of soilcalled interface. This paper deals with the formulation of a nonassociated elastoplastic model forinterface behaviour under monotonic and cyclic conditions. Two plastic surfaces are employed: anexternal surface subjected to isotropic hardening and an internal one subjected to a purely kinematicrotational hardening. Flow rule is similar to that used in Cam Clay model but differs if hardening orsoftening conditions are involved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
