Nonlinear Metamaterials with Multiple Local Mechanical Resonators: Analytical and Numerical Analysesist of lumped masses connected through nonlinear springs. Each cell is embedded with multiple local resonators having different parameters. In one case the local resonators are assumed to be linear and in another case they are nonlinear. The dispersion equation for the system is derived analytically

Nonlinear Vibration Analysis of Metamaterial Honeycomb Sandwich Structures with Negative Poisson’s Rs to investigate the nonlinear dynamic response and periodic vibration characteristic of a simply supported concave hexagonal honeycomb sandwich plate with negative Poisson’s ratio. The plate is subjected to its in-plane and transverse excitation. The curvilinear coordinate frame, Poincaré map, and

Numerical Simulations in Nonlinear Elastic Metamaterials with Nonlocal Interaction) and nonlinear interactions. The dynamic behavior of the newly defined structure is described by nonlinear integro-differential equation of motion. Numerical simulations, comparing the linearized model and the nonlinear one, unveil the arising of wave-stopping and backward propagation phenomena.

Nonlinear Dynamic Response of Nanocomposite Cantilever Beamsilevers made of a thermoplastic polymer and high aspect ratio CNTs are subject to a primary resonance base excitation. The experimentally obtained frequency-response curves highlight the effects of the CNT/polymer stick-slip energy dissipation on the nonlinear macroscopic dynamic response of the nan

Parametric Vibrations of Functionally Graded Sandwich Plates with Complex Formsstudied. Different types of lamination schemes were considered: a sandwich plate with FGM face sheets and isotropic (metal or ceramic) core and a plate with a FGM core and ceramics or metal on top and bottom face sheets. Effective material properties are computed according to Voigt’s rule in thickne

Nonlinear Vibration Analysis of a Sandwich Beam and Assessment of the Dynamic Behaviorcies and amplitudes. The analyses consider the thin face-sheets of the sandwich plate which are subject to in-plane compressive load lower than the estimated critical value for the local buckling, but the plate is also subject to vibration in specific frequency causing variation of the load amplitud
