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 ...
Experimental study of fluid structure interaction effects on metal plates under fully developed laminar flow
(Monterey, California. Naval Postgraduate School, 2011-12)
The development of a reference test case with repeatable and accurate results is of paramount importance for the validation of numerical Fluid Structure Interaction (FSI) models and simulations. In this study, a new ...
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 ...
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 ...
Dynamic response of soldered electronic components under impact loading
(Monterey, California. Naval Postgraduate School, 2011-12)
The objective of this research was to analyze the effects of impact loading on electronic component failure. A standard fiberglass composite printed circuit board (PCB) card was used in two impact tests. The first test ...
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 ...
