Abstract
This study investigated the peak pressure applied to a composite structure under various transient velocity profiles, fluid boundary conditions, as well as structural geometric configurations and material properties. Then, the resultant dynamic responses of the composite structures were investigated. The study was conducted by modeling fluid-structure interaction using the finite-element and finite-volume analysis technique. The results showed that the peak pressure and the resultant stresses in the composite structures are significantly dependent on the accelerating state as well as fluid boundary conditions. The peak stresses determined in this study were between three and 16 times larger than the steady state stress for the given fluid acceleration profile.
