Abstract : Several different fields are involved in rupture of pressurized metallic vessels (mechanics but also thermodynamics as well as fluid mechanics) but few studies take into account all of them. Consequently a numerical study of a metallic plate submitted to dynamic solicitation 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, elasto-viscoplastic and damage laws, and a depressurization depending on breach opening
Keywords : dynamic elastoviscoplastic damage
