โœฆ Synopsis

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.

Strain hardening is introduced in the failure assessment diagram by studying two simple collapse models. These models together with the new failure curves are used both to predict the maximum load of different types of specimens and to assess the stability of these specimens under controlled displac

This paper presents the multiaxial formulation of a plasticity model for sand under cyclic shearing. The model adopts a kinematic hardening circular cone as the yield surface and three non-circular conical surfaces corresponding to the deviatoric stress ratios at phase transformation, peak strength
