Study of Fluid Effects on Dynamics of Composite Structures

This study investigates the effect of fluid-structure interaction on dynamic responses of submerged composite structures subjected to a mechanical loading. The research focuses on finding various parameters that affect the transient dynamic responses of these structures. Coupled fluid-structure interaction analyses of composite structures surrounded by a water medium are conducted numerically for various parametric studies, and their results are compared to those of dry structures. Furthermore, modified dry structural models are developed to represent the dynamic responses of the same structures under water with a reasonable accuracy. Those models promise to be beneficial to predict structural behaviors under water without an expensive computational or experimental cost.
