A numerical study into the dynamic behaviour of hybrid pressurised barrels manufactured from GLARE (Glass fibre Reinforced laminate) has been performed using the Arbitrary-Lagrangian-Eulerian (ALE) method that accounts for fluid structure interaction within the explicit finite element software RADIOSS. The results high-lighted the importance of the geometrical features of the closed barrel when assessing the shock wave propagation of the blast wave. Also the effect of pre-pressurisation was studied which proved significant in providing additional internal energy to the system. It was concluded that pressurisation should be accounted in all future studies to model the dynamic crack growth and structural integrity of typical aircraft structures subjected to blast.

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.

This study investigated the effect of fluid-structure interaction on dynamic responses of submerged composite structures subjected to a mechanical impact loading. The research was focused on finding various parameters that affected the transient dynamic responses of the submerged composite structures. To this end, coupled fluid-structure interaction analyses of composite structures surrounded by a water medium were conducted numerically for various parametric studies and their results were compared with those of dry (i.e., in air) structures in order to understand the role of each parameter under study. Furthermore, modified dry structural models were developed to represent the dynamic responses of the same structures under water with a reasonable accuracy. Those models would be beneficial to predict the structural behaviors under water without an expensive computational or experimental cost.
