Behaviour of metallic plates subjected to explosions. Experiments and modelling in the field of large deformations and rupture
Abstract
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.
