Vibrations suppression of a Euler-Bernoulli beam in contact with a fluid using piezoelectric actuators

In this article the vibration suppression of a beam under heavy fluid loading will be addressed. The main novelty of this study is suppressing the beam vibrations in contact to the fluid utilizing piezoelectric sensors and actuators. The piezoelectric sensors and actuators are attached to the beam and utilized to suppress the beam vibrations. In this study, the fluid has a free surface which complicate handling the problem. We avoid discretizing the domains. The stabilizations objectives (for both beam vibrations and fluid coupled motion) will be accomplished utilizing only the piezoelectric actuators attached to the beam.
