“…The constitutive equations of the PZT patch are [16][17][18]: where S X and S Y are strains, T X and T Y are stresses, ĒPZT = E PZT (1 + ni) is the elastic modulus at zero electric field, n is the mechanical loss factor, ν PZT is the Poisson's ratio, d 31 and d 32 are the piezoelectric constants in the x and y directions, respectively, εT 33 = ε T 33 (1 − δi) is the dielectric constant at zero stress, D is the electric displacement, δ the dielectric loss factor and i = √ −1. The electric current passing through the PZT patch can be considered to be given by…”

“…The idea here is an extension of other works of the present authors [16,17]. It is focused to find out the required PZT actuator input voltages to produce a desired vibration reduction at pre-selected locations of the vibrating structure.…”

“…In another paper, studied by the same author, the potential of the detection of flexural damage state in the lower part of the midspan area of a simply supported reinforced concrete beam using piezoelectric sensors is analytically investigated [11]. The problem of comparing two different smart damping techniques using the numerical modelling of the electromechanical impedance for plate structures with piezoelectric sensors is addressed [12].…”
