“…[26–32]. The utilization of annular/circular plates in the form of sandwich plates has been suggested in a good number of research reports [33–36] especially for having their (annular/circular plates) improved strength-to-weight ratio and energy-absorbing capacity. Further advancement in the design of annular/circular plates is achieved by implementing the concept of the smart structure where the piezoelectric materials are used to incorporate the self-sensing and self-controlling capabilities of the plates.…”

This work presents the shear-based attenuation of vibration of an annular sandwich plate using two different shear mode piezoelectric fiber composite (PFC) actuators namely Shear Actuated Fiber Composite (SAFC) and Balanced Laminate of PFC (BL-PFC). A conventional shear mode monolithic piezoelectric (PZT5H) actuator is also used, and a comparative study on the shear actuation capabilities of all three shear actuators is performed to address the best one for shear-based control of the annular sandwich plate. Every actuator is used in the form of an actuator laminate that is inserted at the core of the sandwich plate in the form of the patches, where a fruitful arrangement of the patches and a shear-based control strategy are presented for effective attenuation of vibration of the sandwich plate according to the velocity feedback control law. First, the effective properties of the actuator laminate are determined using the Uniform Field Method. Next, a closed-loop finite element model of the sandwich plate is developed based on the layer-wise shear deformation theory. Subsequently, the suitability of the present arrangement of shear actuator patches and the shear-based control strategy are substantiated. This arrangement of the actuator patches is further optimized for every shear actuator, and the corresponding shear actuated resonant displacement-amplitudes of the sandwich plate are evaluated. These results reveal lesser actuation capability of the SAFC than that of the PZT5H while the BL-PFC is the best one for shear-based attenuation of vibration of the annular sandwich plate.

“…The vibration of circular sandwich panels has had relatively few investigations. Mirza and Singh studied the axisymmetric vibration of circular sandwich panels by introducing two deformation functions to solve the governing equations [4]. Kao and Ross obtained fundamental frequencies of clamped and simply supported circular sandwich panels by developing the governing equations from a variational theorem [5].…”

Axisymmetric and non-axisymmetric modes of vibration of circular sandwich panels are investigated by applying first-order shear theory (Mindlin-Reissner Plate). Solutions are obtained for boundary conditions with free, simply supported, and clamped edges. Numerical finite element method (FEM) simulation using ABAQUS is applied to validate the analytical modeling. Both analytical and numerical calculations are compared with experimental measurements of the first few modes of vibration; the frequency differences are less than 4%.
