Vibration suppression of composite plate and determination of settling time

The objective of this numerical analysis is to find the dynamic response at the centre of a composite plate and to find out the settling time for vibration within a tolerance level at the centre. The dynamic responses are simulated for different gain values. Effect of variation in the size and location of PVDF patch on the vibration response and settling time is also studied.

Simply supported plate in fixed-free-fixed-free boundary condition is bonded with PVDF actuator patches of different size and configuration [Figure 22.1].
