ABSTRACT: The applicability of the Perzyna and Duvaut-Lions viscoplastic models in the simulation of the sand behavior under high strain rates is examined and results of both model are compared. In comparison with Perzyna model, Duvaut-Lions viscoplastic model has been investigated less; here, capability of this model on simulation of high strain uniaxial strain tests conducted by Split Hopkinson Pressure Bar is studied and a simple modification on its viscoplastic strain rate equation is presented.
RÉSUMÉ: Les modèles viscoplastiques Perzyna et Duvaut-Lions sont étudiés et comparés pour de la déformation rapide de sable. Par rapport au modèle Perzyna, le modèle Duvaut-Lions est moins étudié dans la littérature scientifique disponible. Dans cette recherche, la capacité du modèle Duvaut-Lions de simuler la déformation rapide uniaxe élaborée dans des expériences Split Hopkinson est étudié et une modification simple et efficace déformation est présentée.
