An experimental and numerical study of metallic circular plates subjected to dynamic loads leading to rupture is presented. Various loads have been produced by different kinds of explosions : deflagrations or detonations of stoichiometric hydrogen-oxygen mixtures. A sample response modelling is implemented with the MSC MARC software, using axisymmetrical shell elements and elasto-viscoplastic laws and including damage.
