Theses and Dissertations
Heat conduction analysis of randomly dispersed singlewalled carbon nanotubes
(Monterey, California. Naval Postgraduate School, 2007-06)
This thesis studies the effective thermal conductivity of randomly oriented, percolated carbon nanotubes. To that end, a multiscale analysis approach was adopted. At the nanoscale, molecular dynamics simulation was performed ...
Analytical modeling of composite-to-composite (scarf) joints in tension and compression
(Monterey, California. Naval Postgraduate School, 2007-06)
Fracture mechanics-based multi-level computational modeling and simulation techniques were developed to predict failure strengths of composite scarf joints under tension or compression. Global, local, and element level ...
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 ...
Study of load transfer and fracture on composite-to-metal-wire joints
(Monterey, California. Naval Postgraduate School, 2009-03)
In order to connect a composite structure to a metallic structure, a hybrid composite/metal-wire laminate has been considered. Such a hybrid laminate raises a question of interface strength between the composite layer and ...
Scarf joint modeling and analysis of composite materials
(Monterey, California. Naval Postgraduate School, 2009-06)
The objective of this study is to investigate joint strength of the scarf joint configuration, constructed from carbon and glass woven fabric hybrid laminates, with different material combinations. Glass/glass, glass/carbon, ...
A validation of a molecular dynamics simulation in determining the thermal conductivity of a La-Zr pyrochlore
(Monterey, California. Naval Postgraduate School, 2008-12)
Semiconductors continue to shrink in size and are now nearing the performance limits of some traditional materials. Silicon Dioxide, which has been used extensively as a gate insulator in MOSFETs, is one such material ...
Experimental study of composites and metal-wire joints
(Monterey, California. Naval Postgraduate School, 2008-09)
In order to join a composite structure to a metallic structure, the metal-wire layers were co-cured with composite layers using the Vacuum Assisted Resin Transfer Molding (VARTM). Then, the interface fracture strength was ...
The effects of carbon nanotube reinforcement on adhesive joints for naval applications
(Monterey, California. Naval Postgraduate School, 2009-12)
The adhesive joint strength of various carbon fiber composite and steel joints was studied using Mode II fracture strength testing. The effect of the addition of multi-walled carbon nanotubes (MWNTs) to the adhesive was ...
Investigation of the effect of fuselage dents on compressive failure load
(Monterey, California. Naval Postgraduate School, 2007-03)
The main motivation for this thesis study is that significant workload for aging transport aircrafts is related to dent removal from fuselages. This thesis is a preliminary investigation of aircraft fuselage dents using ...
An experimental study of fluid structure interaction of carbon composites under low velocity impact
(Monterey, California. Naval Postgraduate School, 2009-12)
The effect of fluid force on the natural frequencies and damping ratios of vibrating structures in contact with fluid is known as the Fluid Structure Interaction (FSI) problem. It can be interpreted as an added mass to the ...
