A Multi-Physics Finite Element Analysis of Round Pin, High Power Connectors
(2010-04-15)
In the past decade, the general public’s means of transportation has begun to undergo a radical transformation, moving away from only using gasoline and moving toward using a combination of gasoline and electricity. This ...
Terminal Ballistics of Composite Panels and Verification of Finite Element Analysis
(2011-07-29)
Composite materials are becoming more prevalent in a wider range of applications due to the inherent advantages afforded by their strength to weight ratio over more traditional engineering materials such as metals. As such, ...
Flexural Response of Syntactic Foam Core Sandwich Structures: Effects of Graded Face Sheets and Interpenetrating Phase Composite Foam Core
(2011-05-09)
In this thesis, flexural responses of sandwich structures with different syntactic foam core architectures are studied. The syntactic foam core is made by dispersing hollow glass microballoons in epoxy matrix at different ...
A Non-contact Method for Sensing Tire Contact Patch Deformation Using a Monocular Vision System and Speckled Image Tracking
(2011-05-16)
A full-field, non-contact deformation sensing system was developed with an application for tires. Using an image tracking algorithm, in-plane displacements and their gradients were calculated. Furthermore, the effects of ...
State of Charge Estimation for Advanced Batteries: Reduced Order Electrochemical Modeling with Error Compensation
(2011-11-17)
Advanced battery management systems are essential for efficient electrification of vehicles. Correct state of charge (SOC) estimates will maintain a battery within its charge limits and extend its usable life. Existing SOC ...
Health Monitoring for Damage Initiation & Progression During Mechanical Shock in Electronic Assemblies
(2009-02-23)
Electronic products may be subjected to shock and vibration during shipping, normal usage and accidental drop. Highstrain rate transient bending produced by such loads may result in failure of fine-pitch electronics. Current ...
Heuristic Optimization Methods for the Characterization of Dynamic Mechanical Properties of Composite Materials
(2009-02-23)
Generally speaking, of the fundamental dynamic mechanical properties - mass, damping, and stiffness, damping is usually the most difficult to quantify. This is perhaps particularly true for composite materials which tend ...
Static, Dynamic and Acoustical Properties of Sandwich Composite Materials
(2009-02-23)
Sandwich composite materials have been widely used in recent years for the construction of spacecraft, aircraft, and ships, mainly because of their high stiffness-to-weight ratios and the introduction of a viscoelastic ...
Prognostics Health Management and Damage Relationships of Lead-Free Components in Thermal Cycling Harsh Environments
(2008-09-09)
There has been a growing interest in the area of health monitoring of electronics in order to predict the failure and provide warnings. Existing Prognostics Health Management methodologies are very reactive in nature and ...
Relative Positioning of Unmanned Ground Vehicles Using Ultrasonic Sensors
(2008-09-09)
In this thesis, a Global Positioning System/Inertial Navigation System (GPS/INS) is developed and applied to a tracked Unmanned Ground Vehicle (UGV) to provide estimates of position, heading, and velocity. The navigation ...
