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 ...
UNIFORM AND MULTI-GRID MODELING OF ACOUSTIC WAVE PROPAGATION WITH CELLULAR AUTOMATON TECHNIQUES
(Monterey, California. Naval Postgraduate School, 2013-03)
The Cellular Automaton (CA) method is an alternative computational technique used in understanding the behavioral response of dynamic systems. It allows great flexibility in the application of various types of boundary ...
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 ...
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 ...
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 ...
The Influence of Shock-Induced Air Bubble Collapse resulting from Underwater Explosive Events
(Monterey, California. Naval Postgraduate School, 2012-06)
During an underwater explosion (UNDEX) event, a cavitation zone is created which alters the shockwave propagation parameters through this region. A cavitation zone is generally comprised of air bubbles whose material ...
Dynamic response of composite structures underwater
(Monterey, California: Naval Postgraduate School, 2013-09)
This paper presents a comparison of the dynamic response of composite structures that are subjected to low velocity impacts while being suspended both in air, and submerged in water. As the U.S. Navy continues to use larger ...
Development of carbon nanotube-based sensor to monitor crack growth in cracked aluminum structures underneath composite patching
(Monterey, California: Naval Postgraduate School, 2014-06)
This paper presents the design of a carbon nanotube-based sensor to detect crack propagation in aluminum structures underneath composite patching. Initial tests are utilized to determine the correct procedure and materials ...
