Abstract
An active constrained layer system includes a passive viscoelastic damping material positioned on top of a substrate. An active piezoelectric layer is positioned on top of the passive viscoelastic damping material. An edge element physically connects the active piezoelectric layer to the substrate to transmit active forces and moments from the piezoelectric layer to the substrate. The novel edge element yields higher active control from the piezoelectric layer, while preserving the damping capacity of the passive viscoelastic layer. The edge element may be implemented in a variety of ways, including an edge element clamp structure and an edge element post structure.
