An analytical model is proposed for a cantilever beam system with active piezoelectric fiber reinforced composite (APFRC) damping layers. Two different types of APFRC damping layers, namely APFRC-IDE and APFRC-LE, are used in this investigation. A numerical study is conducted to investigate the effects of major parameters of APFRC damping layers and electrode pattern on the dynamic characteristics of the beam system. It is noted that for the present case, the peak value of damping factor is attained at θ=0°for the APFRC-IDE and at θ=45° for the APFRC-LE. The ratio between these two peak values is close to that between the coefficient en for the APFRC-IDE and e_(31) for the APFRC-LE.
