Response envelopes of the elasto-plastic S-CLAY1 model
Résumé
In this paper, the features of S-CLAY1 model are explored through identification of the so-called response envelopes, which is very useful way of studying the incremental behaviour of a constitutive model. To highlights the effect of anisotropy induced by the S-CLAY1 model formulation a systematic comparison to the response of the well known isotropic Modified Cam-Clay model is performed.
