Modeling and analysis of periodic and quasi-periodic sandwich structures with internal resonators

Resumo

The use of internal resonators, acting as vibration absorbers, for low-weight closed periodic structures,
such as honeycomb core sandwich plates is an interesting alternative for vibration control treatments that do not
rely on significant strains on the host structure. One of the main challenges for the study of such solutions is the
computational cost required for their analysis, design and optimization. This work presents a modeling strategy and
procedure applied for periodic and quasi-periodic sandwich structures with internal resonators aiming at reducing
the required computational cost while still allowing parametric analysis, design and optimization.
