Fluid-structure interaction effects resulting from hull appendage coupling
(Monterey California. Naval Postgraduate School, 2005-09)
In previous work conducted in the modeling and simulation of ships subjected to underwater explosions, there has been some debate over the influence that hull appendages have upon the dynamic response of a multi-degree-of-freedom ...
Numerical Study for Optimum Parameters of Bonded Composite Repairs of Cracked Aluminum
(Monterey, California. Naval Postgraduate School, 2012-06)
This thesis used Finite Element Analysis to model a cracked aluminum panel repaired with a bonded composite patch using the minimization of energy release rate in mode I crack growth conditions to determine effectiveness ...
Numerical study of effects of fluid-structure interaction on dynamic responses of composite plates
(Monterey, California. Naval Postgraduate School, 2009-09)
Composite materials are seeing increased use in structural applications because of their various benefits. When composite structures are employed in a water environment, their dynamic responses are greatly affected by the ...
FLUID-FILLED STRUCTURE WITH MULTIPLE COMPOSITE COMPARTMENTS SUBJECTED TO LOW-VELOCITY IMPACT
(Monterey, CA; Naval Postgraduate School, 2018-06)
The focus of this study was to investigate the dynamic response and the fluid-structure interaction (FSI) in a fluid-filled composite structure with multiple compartments subjected to a low-velocity impact. The compartments ...
Dynamic failure of sandwich beams with fluid-structure interaction under impact loading
(Monterey, California. Naval Postgraduate School, 2010-12)
The objective of this research is to examine the added mass effect that water has on the dynamic response of a sandwich composite under impact, particularly impact leading to failure. Because sandwich composites are much ...
Free Vibration Response Comparison of Composite Beams with Fluid Structure Interaction
(Monterey, California. Naval Postgraduate School, 2012-09)
The analysis of the dynamic response of a vibrating structure in contact with a fluid medium can be interpreted as an added mass effect known as the Fluid Structure Interaction (FSI) problem. This effect is critical in the ...
Glass fiber resin composites and components at arctic temperatures
(Monterey, California: Naval Postgraduate School, 2015-06)
Glass fiber reinforced composites (GFRC) are used in a wide variety of applications within the U.S. Navy. With a potential increase in arctic operations in the Navy’s future, it is important to understand how GFRCs will ...
Hydrodynamic drag force measurement of a functionalized surface exhibiting superhydrophobic properties
(Monterey, California: Naval Postgraduate School, 2016-12)
With superhydrophobic properties being extended to a variety of metallic substrates through the process of ablation due to femto-second laser surface processing (FLSP), it is important to understand the hydrodynamic benefits ...
Numerical analysis of ice impacts on azimuth propeller
(Monterey, California: Naval Postgraduate School, 2013-09)
Incorporating an azimuth/podded propulsion into an ice-capable ship brings concern in the propellers durability and lifecycle. An ice impact model was constructed to have a better understanding of collisions occurring ...
Fluid Structure Interaction Effects on Composites Under Low Velocity Impact
(Monterey, California. Naval Postgraduate School, 2012-06)
In this study composite materials were tested in different fluid environments to determine the role of Fluid Structure Interaction with these composites under a lower velocity impact. The purpose of this research is to ...
