Component Modal Analysis of a Folding Wing
(2011)This thesis explores the aeroelastic stability of a folding wing with an arbitrary number of wing segments. Simplifying assumptions are made such that it is possible to derive the equations of motion analytically. First, ... -
Efficient Solution of Unsteady Nonlinear Flows Using a Multiple Zone Harmonic Balance Technique
(2010)An efficient two-dimensional multiple zone harmonic balance solver for calculating unsteady nonlinear flows is presented. The solver adapts Roe's flux difference splitting algorithm such that it can be used to discretize ... -
Experimental Investigation and Modeling of Scale Effects in Micro Jet Pumps
(2011)Since the mid-1990s there has been an active effort to develop hydrocarbon-fueled power generation and propulsion systems on the scale of centimeters or smaller. This effort led to the creation and expansion of a field of ... -
Mass Transfer in Multi-Phase Single Particle Systems
(2011)This thesis addresses mass transfer in multi-phase single particle systems. By using a novel technique based upon the micropipette, the dissolution of liquid and gas droplets in a liquid medium can be observed. Three classes ... -
Nonlinear Electroelastic Dynamical Systems for Inertial Power Generation
(2011)Within the past decade, advances in small-scale electronics have reduced power consumption requirements such that mechanisms for harnessing ambient kinetic energy for self-sustenance are a viable technology. Such devices, ... -
Springback Analysis for Rod Bending in Spinal Fusion Surgery Applications
(2010)Spinal fusion is quickly becoming a common surgical operation in today's medical field. A major component of spinal fusion surgery is the use of metal rods. These rods, which are made of titanium or stainless steel, must ... -
Stability Analysis of Time Delay Systems Using Spectral Element Method
(2010)The goal of this work is to develop a practical and comprehensive methodology to study the response and the stability of various delay differential equations (DDEs). The development of these new analysis techniques is motivated ... -
STIFFNESS CALIBRATION OF ATOMIC FORCE MICROSCOPY PROBES UNDER HEAVY FLUID LOADING
(2010)This research presents new calibration techniques for the characterization of atomic force microscopy cantilevers. Atomic force microscopy cantilevers are sensors that detect forces on the order of pico- to nanonewtons ... -
The Ductile to Brittle Transition in Polycarbonate
(2011)An advanced bulk constitutive model is used with a new cohesive zone model that is stress state and rate-dependent in order to simulate the ductile to brittle failure transition in polycarbonate. The cohesive zone model ... -
The natural emergence of vascular design with turbulent flow
(2010)Here we show that vascular design emerges naturally when a volume is bathed by a single stream in turbulent flow. The stream enters the volume, spreads itself to bathe the volume, and then reconstitutes itself as a single ...
