Nonlinear damping laws preserving the eigenstructure of the momentum space for conservative linear PDE problems: a port-Hamiltonian modelling
Résumé
Application to morphing in sound synthesis with the mutation of damping material properties leads us to introduce a class of nonlinear damping models operating on the momentum equation of the Hamiltonian formulation of a conservative mechanical PDE; the modal decomposition of the original linear vibrating structure is useful to analyze the preserved geometric features.
