.. _R5.03.35: **r5.03.35** Integration of Maxwell's viscoelastic behavior relationship (VISC_MAXWELL and VISC_MAXWELL_MT) ================================================================================================================== **Summary** This paper describes the development of Maxwell's law of viscoelastic behavior. Maxwell's law (keyword VISC_MAXWELL) is a basic viscoelastic law. Its variant (keyword VISC_MAXWELL_MT) includes a variation of its parameters with porosity according to a Mori-Tanaka homogenization law. This last law is therefore only available for poromechanical models (THM). .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Introduction Relation_continue _volution_des_param_tres_pour_la_loi_VISC_MAXWELL_MT Int_gration_de_la_relation_de_comportement Bibliographie
