Comparison of approaches for determining the failure of stiffened cylindrical shells
(Massachusetts Institute of Technology, 2002)
Shape optimization theory and applications in hydrodynamics
(Massachusetts Institute of Technology, 2004)
The Lagrange multiplier theorem and optimal control theory are applied to a continuous shape optimization problem for reducing the wave resistance of a submerged body translating at a steady forward velocity well below a ...
Ultrasonic wave propagation in thick, layered composites containing degraded interfaces
(Massachusetts Institute of Technology, 2005)
The ultrasonic wave propagation of thick, layered composites containing degraded bonds is investigated. A theoretical one-dimensional model of three attenuative viscoelastic layers containing two imperfect interfaces is ...
Manning and automation of naval surface combatants : a functional allocation approach using axiomatic design theory
(Massachusetts Institute of Technology, 2000)
The design of ships is an inherently complex process. This complexity is significantly increased when the particular ship being designed is a naval surface combatant. The ship design process is traditionally viewed as a ...
Ship hull plating weld misalignment effects when subjected to tension
(Massachusetts Institute of Technology, 2001)
Plastic resistance of thin-walled prismatic tubes under large twisting rotations
(Massachusetts Institute of Technology, 2000)
Effect of hull-to-bulkhead flexible connection on blast resistance of double hulled ships
(Massachusetts Institute of Technology, 2004)
The use of double hull construction is commonplace within the shipping industry though it is largely unexploited within naval vessels. The Impact and Crashworthiness Lab at MIT has proposed the use of adaptive sandwich ...
An experimental study of the oil evolution in critical piston ring pack regions and the effects of piston and ring designs in an internal combustion engine utilizing two-dimensional laser induced fluorescence and the impact on maritime economics
(Massachusetts Institute of Technology, 2004)
Faced with increasing concern for lubricating, oil consumption and engine friction, it is critical to understand the oil transport mechanisms in the power cylinder system. Lubricating oil travels through distinct regions ...
Pipe circularity reformation via line heating
(Massachusetts Institute of Technology, 2001)
Fabrication of pipes requires the use of several manufacturing processes, such as bending, welding, drilling and wringing. However, in most cases the circular ends deviate from true circles and need reformation to be welded ...
Forces and moments due to unsteady motion of an underwater vehicle
(Massachusetts Institute of Technology, 2003)
This research examines the effect of unsteady motion on the forces and moments experienced by an underwater vehicle in shallow water. The test platform is the REMUS Autonomous Underwater Vehicle developed by the Woods Hole ...
