Abstract

Numerical studies undertaken to determine the structural intensity for active vibration of plates bonded with piezoceramic patches are presented. The formulation, which is based on finite- difference schemes, allows for thin isotropic plates with general boundary conditions. Active and reactive intensities are computed for the different cases, in which the considered plate is excited by a planar sound field and/or one or more piezoceramic patches. The numerical results indicate the importance of considering reactive intensities for active vibration control applications.
