.. _U2.03.09: **u2.03.09** Overview of soil and rock behavior models, joints ============================================================================== **Summary:** The objective of this document is to provide an overview of the modeling possibilities available to the user in modeling the behavior of soils and rocks, to which the behavior of joints has also been added to describe the interfaces between geomaterial environments. Different choices are always possible and the aim of this document is not to replace the engineer's analysis but to allow him to more easily choose the modeling options, according to the needs and the tools available, and to guide him towards more specific documents. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Introduction La_mod_lisation_du_comportement_en_fonction_du_type_d_analyse___mener Ce_que_Code_Aster_ne_sait_pas__encore__faire R_f_rences Description_des_versions_de_ce_document
