Résumé / Abstract
The derivation of some class of generalized mechanical models relies on a specific stress expansion with-out anya prioriassumption on the corresponding kinematics. In such situations, their extension to adynamic setting is not easy, especially when deriving the corresponding generalized inertias since thekinematics is unknown. This paper shows how consistent generalized inertias can be obtained throughthe use of a complementary energy principle in elastodynamics. The methodology is then applied toextend a stress-based layerwise plate model in the dynamic setting. This approach is finally validatedthrough modal analysis of various anisotropic composite laminates
