Finite Element Modeling Of Carbon Nanotube Reinforced Polymer Composites And Evaluating Its Thermal Conductivities
(Mechanical Engineering, 2007-08-23)
High thermal conductivity of carbon nanotubes has motivated us to study and understand the thermal mechanisms in nanocomposites. Though several theoretical models predict a high thermal conductivity for CNT reinforced ...
Crashworthiness Design Optimization Using Surrogate Models
(Mechanical Engineering, 2007-08-23)
Despite the advances in computer technology, the enormous computational cost associated with the large-scale and complex nonlinear crashworthiness simulations renders it to be impractical to rely exclusively on computer ...
Airy Stress Function For Two Dimensional Inclusion Problems
(Mechanical Engineering, 2007-08-23)
This thesis addresses a problem of finding the elastic fields in a two-dimensional body containing an inhomogeneous inclusion using the Airy stress function which is determined so that the prescribed boundary condition at ...
Analysis And Optimal Design Of Beams Using Radial Basis Function
(Mechanical Engineering, 2007-08-23)
The application of Multiquadric Radial Basis Function (MQ RBF) in the analysis and optimal design of beams are addressed in this dissertation. For static analysis, a new Least Square Collocation (LSC) method is introduced. ...
Numerical Simulation Of Pulse Detonation Phenomena In A Parallel Environment
(Aerospace Engineering, 2007-08-23)
The objective of this work was to develop a parallel algorithm that would be used in the simulation of the detonation process in the chamber of a pulse detonation engine. The emphasis is laid on reducing computation ...
Study Of Blast Wave Impact On Concrete
(Aerospace Engineering, 2007-08-23)
The past decade has brought an upsurge of terrorist attacks throughout the world. A common form of attack is bombings employed against a civilian structure. These bombs lead to blast waves resulting from high explosive ...
Control And Simulation Of Relative Motion For Aerial Refueling In Racetrack Maneuver
(Aerospace Engineering, 2007-08-23)
This thesis addresses the problem of controlling the receiver aircraft to achieve a successful aerial refueling. For the performance verification of the controller, a new set of nonlinear, 6-DOF, rigid body equations of ...
Freezing-induced Microstructural Changes Of Collagen Scaffolds
(Mechanical Engineering, 2007-08-23)
Understanding the effects of freezing on the functional properties of tissues is critical to cryopreservation of native and artificial tissues, and prognosis after cryotherapies. Although investigations have been performed ...
Computer-aided Patient Specific Treatment Planning Of Cryosurgery For Breast Cancer
(Mechanical Engineering, 2007-08-23)
Cryosurgery, which is to destroy tumors by use of localized freezing, is an emerging treatment modality for breast cancer as the size of detectable tumor becomes smaller due to more frequent use of various diagnostic imaging ...
Modular Multi-scale Assembly System For MEMS Packaging
(Mechanical Engineering, 2007-08-23)
A multi-scale robotic assembly problem is approached here with focus on mechanical design for precision positioning at the microscale. The assembly system is characterized in terms of accuracy/repeatability and calibration ...
