The problem addressed in this paper is that of modeling composite beams excited by distributed piezoelectric actuators. A model based on Reddy's layerwise laminate theory is proposed. Through comparisons with exact wave-dispersion analytical results, it is shown that the model may provide an accurate description of the active beam's response in the high-frequency (short-wavelength) range.
