	A nonlinear model of a structure consisting of a rigid hub and three thin-walled flexible laminated beams is analysed in this paper. It is assumed the considered blades have additional piezoceramic layers embedded into master laminate, so due to elastic specimen deformation an electric field is induced. In the mathematical model of the multi-material blades a full two-way piezoelectric coupling effect involving mutual mechanical and electrical interactions is adopted. Moreover, a nonlinear constitutive relation for piezoceramic material with respect to electrical field is considered to properly model the active structure behaviour when operated in near resonance conditions. The governing equations of the system have been sourced from the previous authors’ research. Next, resonance curve plots of the coupled electromechanical system considering both the blades and the hub dynamics have been prepared. Within the performed studies cases of a fully symmetric and next a slightly mistuned rotor configuration have been discussed.
