Abstract

The dynamic response of an adaptive beam containing embedded mini-devices (sensors and actuators) is investigated analytically and experimentally in this paper. The dynamic model is based on Hamilton's variational principle and the mechanical interactions between the beam and the devices are modeled using Eshelby's equivalent-inclusion method. The dynamic model is verified experimentally, using a cantilever beam made of ALPLEX plastic as host material and piezoelectric devices (PZT-5H) as active mini-devices for sensing and actuation. The experimental setup is outlined and the analytical results are compared with the experimental ones. The capability of mini-actuators to change the dynamic behavior of the adaptive beam is explored for the adaptive stiffening case.
