Damage inspection of isotropic/multi-layer plates by time-frequency analysis of Lamb waves
(University of Missouri--Columbia, 2014) -
Elastic wave absorption in laser-cut acoustic metamaterial plates
(University of Missouri--Columbia, 2016)This dissertation presents the modeling technique for design and analysis of lasercut acoustic metamaterial plates (LCMPs) capable of acoustic/elastic vibration suppression. The conventional acoustic metamaterial plate ... -
Finite-element design of metamaterial beams for broadband wave absorption
(University of Missouri--Columbia, 2015)Metamaterials were first introduced for dealing with electromagnetic waves. By creating a material with negative magnetic permeability and electric permittivity, it is possible to manufacture perfect optical lenses, ... -
Flapping wing dynamics of MAVs : nonlinear modeling and experimental investigation
(University of Missouri--Columbia, 2011)Analysis of the flapping-wing motion of micro air vehicles (MAVs) is a complex problem that involves nonlinear structural analysis coupled with unsteady fluid mechanics analysis. In this study I apply a fully nonlinear ... -
Innovative design of metamaterial structures for elastic wave absorption and structural vibration suppression
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation presents the design procedures, the modeling techniques and the working mechanism of metamaterial structures for wide-band elastic ... -
Linear system identification technique by time series analysis
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Identification of linear dynamical systems using the finite difference time-domain (FDTD) method is inaccurate and problematic. This thesis investigates ... -
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ... -
Nonlinear thermomechanical finite-element modeling, analysis and characterization of multi-turn oscillating heat pipes
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Oscillating heat pipes (OHPs) are promising heat dissipation devices for modern electronic systems due to their high heat transfer rate, simple ... -
Parametric and nonparametric dynamical system identification using laser-measured velocities
(University of Missouri--Columbia, 2014) -
Physical implications of characteristic speeds and waveforms of rails on elastic foundations
(University of Missouri--Columbia, 2012)When a moving load is applied on an elastic rail with an elastic insulator, wave propagation can occur and become problematic after certain characteristic speeds are reached. Research of these waveforms and characteristic ... -
Signal procession of single measurand for dynamical system identification /
(University of Missouri--Columbia, 2017)Accurate damage inspection and reliable health monitoring of dynamical systems rely on accurate dynamical data computation. In theory, if all three variables (i.e., displacement, velocity, and acceleration) of each point ... -
Theory and development of a camera-based noncontact vibration measurement system
(University of Missouri--Columbia, 2012)Dramatic advancement in technologies for high-speed high-resolution digital cameras in recent years enables the development of camera-based full-field noncontact measurement systems for vibration testing of flexible multibody ... -
Wireless signal acquisition and processing techniques for horse lameness detection and evaluation
(University of Missouri--Columbia, 2012)The Equine Lameness Locator(R) (ELL) is a newly developed system that provides a robust and objective method to detect and evaluate equine lameness. To achieve objective lameness evaluation, the system analyzes a horse's ...
