Investigating the effect of fluid-structure interaction on the vibrations of fiber-metal laminated cylindrical shells bonded by piezoelectric actuator and sensor layer

This research examines the vibrations of multi-layer aluminum-metal fiber cylindrical shells with embedded piezoelectric layers that have fluid-structure interaction based on the three-dimensional elasticity theory. Using the state space approach, the equations of motion for simple support boundary conditions were obtained. The natural frequencies of the multi-layer metal fiber cylindrical shell containing the driving fluid were obtained by solving the special frequency equation. The effect of different parameters such as length to radius, fluid velocity, ambient wave number and radius to thickness was investigated for aluminum reinforced with carbon fibers. The volume ratio of composite/metal was considered constant. So far, no research has been done on multi-layered aluminum fiber-metal cylindrical shells with embedded piezoelectric layers that have fluid-structure interaction. It is a very new topic. The consistency and convergence of the results of this research was confirmed by comparing the results of natural frequencies reported in the literature, and the high accuracy of the results of this research is expressed.
