Modeling of damage in a circular plate subjected to dynamic excitation

Abstract

International audienceSeveral different scientific fields are involved in the rupture of pressurized metallic vessels (mechanics but also thermodynamics, as well as fluid mechanics). Yet few studies hâve taken into account all of these aspects. Consequently a numerical study of a metallic plate subjected to dynamic loads is presented in this paper, as well as approaches related to rupture. The modeling is developed with MSC MARC software ; it is based on shell elements and elasto-viscoplastic laws including damage
