Abstract

Dans ce travail, la striction localisée des tôles minces est étudiée en utilisant une analyse de localisation type Marciniak-Kuczynski. Un nouveau critère de plasticité orthotrope est utilisé pour déterminer les limites de formage pour des chemins linéaires de déformation. Par ailleurs l'influence des paramètres rhéologiques du matériau sur les courbes limites de formage (CLF) a été étudiée et analysée ainsi que celui de la surface de charge.
