Finite element analyses have been performed on the representative volume element of piezoelectric elements with interdigitated electrodes (IDE). In these investigations the change of the piezoelectric material properties during polarization has been considered prior to additional service loads, e.g. mechanical loading. The numerical results obtained with a specially coded finite element routine are compared with a reference model given by the so called uniform field model. The model indicates stress concentrations at the tip of the finger electrode, which have been validated by experimental results. The modeling approach presented allows for a better understanding of the overall effects in piezoelectric materials with IDE.

“…The active plate behaviour with PFC actuator layers was analysed by Pietrzakowski (2003;2006) where the vibration control effectiveness was compared depending on the piezocomposite spatial configuration and the fiber volume fraction. The optimisation of the ID electrodes design for active fiber composites was performed using finite element analysis by Bowen et al (2006).…”

In the paper the analysis of random vibration of an actively damped laminated plate with functionally graded piezoelectric actuator layers is presented. The simply supported plate is subjected to stochastic loading represented by a uniformly distributed pressure. The random input is assumed as a Gaussian stationary and ergodic process. The actuators are regarded as a multi-layer structure arranged of piezofiber composite sub-layers. The sub-layers differ each other with amount of PZT (lead-zirconate-titanate) fibers and are stacked to achieve a desired change of the PZT volume fraction through the actuator thickness. The gradation scheme of constituents and material properties are estimated by parabolic and power functions. Numerical simulations are performed to recognize the influence of the applied random excitations and the actuator properties gradations on the characteristics of the stochastic field of active plate deflection i.e. power spectral density, autocorrelation function and variance.

“…The Q of ME laminates is determined by the composite components, 7 the polarization distribution of the piezoelectric core, 8 and the boundary conditions. 9 Thus, with regards to modulation technique applications, it is important to characterize the effective mechanical quality factor Q eff of the multi-push-pull mode laminates and the dependence of the polarization distribution that results from the geometry of the ID-electrodes.…”

The mechanical quality factor and the resonant magnetoelectric (ME) response of multi-push-pull mode Metglas/interdigitated (ID)-electrode/Pb(Zr,Ti)O3 (PZT) ME resonators have been studied as a function of ID-electrode geometry for both sandwich and bimorph configurations. The results show that the mechanical quality factor of the PZT core composite and the effective mechanical quality factor of the ME resonator are increased with increasing ID-electrode spacing. The sandwich resonator was found to exhibit a higher effective mechanical quality factor than the bimorph one.
