.. _R7.01.17: **r7.01.17** Barcelona model ================================ **Summary:** This document presents the formulation and numerical integration of the behavior model. elastoplastic from Barcelona [bib2] __, designed to describe the mechanical behavior of non saturated, especially clays. This model is an extension of the modified Cam-Clay model [bia1] __ taking into account, schematically, the effects of capillary pressure on the elasticity, the reversibility range, and the work-hardening mechanisms observed experimentally on unsaturated soils. The Barcelona model has a total of sixteen settings. Behavioral equations are solved using an integration method implicit in time, implemented in the tool MFront [bib5] __. The use of the model is necessarily linked to the environment HHM [:ref:`r7.01.11 `]. .. toctree:: :numbered: :maxdepth: 2 Notations Introduction Formulation_modele_Barcelone Parametres_modele_Barcelone Integration_numerique_Barcelone Cas_tests_Barcelone Bibliographie_Barcelone Jacobien_Barcelone
