Hydrodynamic response of a composite structure in an Arctic environment
(Monterey, California: Naval Postgraduate School, 2015-06)
Climate change has resulted in an increase in naval activity in the Arctic Ocean. While extensive research has been done on the interaction between different forms of ice and conventional steel hulls, little work has been ...
FAILURE OF COMPOSITE PLATES SUBJECTED TO SHOCK LOADING
(Monterey, CA; Naval Postgraduate School, 2020-12)
Underwater explosions and their associated devastating effects are not new to the U.S. Navy. Accurately modeling and scaling them for research and development, however, are areas in need of further study as large explosions ...
STUDY OF COMPOSITE STRUCTURES SUBJECTED TO UNDERWATER SHOCK LOADING
(Monterey, CA; Naval Postgraduate School, 2021-12)
Underwater explosions (UNDEX) produce severe and complex loadings in naval applications. Increased use of composite materials in naval applications requires better understanding of how composite structures will respond and ...
Fluid-structure interaction of channel driven cavity flow
(Monterey, California: Naval Postgraduate School, 2016-06)
An experimental setup was developed for channel driven cavity flow in order to study the fluid-structure interaction and provide benchmark data for validation of numerical fluid-structure interaction models. The channel ...
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 ...
An experimental study of fiberglass composites containing metal wire joints
(Monterey, California. Naval Postgraduate School, 2009-09)
The U.S. Navy has been incorporating increasing amounts of composite materials during construction, especially in the areas of submarine sails and surface ship superstructures. The benefit of using composite material ...
Transient dynamic response and failure of composite structure under cyclic loading with fluid structure interaction
(Monterey, California: Naval Postgraduate School, 2014-09)
With the growing interest in using composites in naval shipbuilding, it is crucial to understand the behavior of structures, especially the Fluid Structural Interaction (FSI) aspect of the composites under dynamic loading, ...
Fluid structure interaction effect on sandwich composite structures
(Monterey, California. Naval Postgraduate School, 2011-09)
The objective of this research is to examine the fluid structure interaction (FSI) effect on composite sandwich structures under a low velocity impact. The primary sandwich composite used in this study was a 6.35-mm balsa ...
FORECAST VALIDITY OF ALUMINUM AND STEEL MECHANICAL PROPERTY TRENDS BASED UPON MICROHARDNESS BEHAVIOR
(Monterey, CA; Naval Postgraduate School, 2019-12)
Most metals used in naval applications are exposed to significant ultraviolet radiation and moisture; the most commonly constructed metals, steel and aluminum, are expected to lose their designed mechanical property integrity ...
TRIBOELECTRIC GENERATOR FOR ENERGY HARVESTING
(Monterey, CA; Naval Postgraduate School, 2019-12)
The open ocean and coastal environments provide an abundant amount of unharvested energy. It would be powerful if the U.S. Navy could harness more of the ocean’s tidal movements, wave oscillations, and vibrations to power ...
