Abstract
The distribution of the energy of a piezoelectric actuator between normal modes (Lamb waves) as a function of the source parameters and frequency is studied by solving the dynamic contact problem of the interaction between a flexible piezoelectric patch and a flexible elastic substrate with explicit representations for the excited traveling waves. Zones of the maximum and minimum energy of the fundamental modes are determined in the “oscillation frequency-piezoelectric patch width” plane.
