Nonlinear interface effects in multilayered structures: vibro-acoustic modeling and experimental analysis
Antoine Demiquel, Kerem Ege, Emmanuel Gourdon
This paper presents an experimental and theoretical study of the nonlinear behavior of imperfect interfaces in multilayer structures using an equivalent vibro-acoustic approach. Th…
Gradient catastrophe and Peregrine soliton in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
We explore the generation of extreme wave events in mechanical metamaterials using the regularization of the gradient catastrophe theory developed by A. Tovbis and M. Bertola for t…
Envelope vector solitons in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
In this paper, we employ a combination of analytical and numerical techniques to investigate the dynamics of lattice envelope vector soliton solutions propagating within a one-dime…
Modulation instability in nonlinear flexible mechanical metamaterials
Antoine Demiquel, Vassos Achilleos, Georgios Theocharis +1
In this paper, we study modulation instabilities (MI) in a one-dimensional chain configuration of a flexible mechanical metamaterial (flexMM). Using the lumped element approach, fl…
