Advanced analysis and design of polymer sheet extrusion
(University of Missouri--Columbia, 2007)A manufacturing process design methodology is presented which can be used to improve the production of polymer components manufactured via the extrusion. The design methodology employs polymer process modeling, design ... -
Characterization of mechanical properties and study of microstructures of friction stir welded joints fabricated from similar and dissimilar alloys of aluminum
(University of Missouri--Columbia, 2007)The objective of this research was to characterize the mechanical properties and study the microstructures of the friction stir welded joints to obtain the optimum process conditions that would result in the desired ... -
Characterization of mechanical properties of fused deposition modeling manufactured polycarbonate composites
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The use of composites in all products - from sporting goods to bridges to satellites - is increasing due to the ability of composite structures to ... -
A comparison of modeling techniques: using the finite element method to determine local displacements in a human hip
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Artificial hip implant surgery is required by approximately 120,000 Americans each year. A typical hip replacement requires the surgical insertion of ... -
Design optimization and efficiency modeling of a hot gas vane motor
(University of Missouri--Columbia, 2007)The purpose of this research is to model and analyze the dynamics of a hot gas vane motor for design optimization work. The pneumatic motor is a portable direct drive actuator that is intended as an alternative to ... -
Development of tailored preform processing technology for net-shape manufacturing of large monolithic structures
(University of Missouri--Columbia, 2007)The aim of the present research effort involves exploration of a new processing approach, "Tailored Preform Processing (TPP)" technology for net-shape manufacturing of monolithic structures for the transportation industry. ... -
Direct contact heat exchanger development
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The purpose of this work was to develop tools that guide the design of a direct contact heat exchanger for small-scale commercial and/or residential ... -
Elastic property prediction of short fiber composites using a uniform mesh finite element method
(University of Missouri--Columbia, 2007)This thesis presents a uniform method to determine the elastic material non-isotropic properties of fiber reinforced composite materials. This method employs a uniform array of custom 3D displacement based elements that ... -
Electrostatically actuated and bi-stable MEMS structures
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Bistable compliant micro-structures offer a tremendous advantage in the industry today, as these structures have an ability to maintain their shape ... -
Experimental and analytical study on two-phase impingement cooling with and without electric field
(University of Missouri--Columbia, 2007)Among the thermal management solutions for power electronics, two-phase jet or spray impingement cooling are two promising candidates. In this study, electrohydrodynamic atomization (EHDA) method is used to generate spray ... -
Failure of transparent polymer composite laminated glass panels under impact loading
(University of Missouri--Columbia, 2007)Historically, windows and other facilities during hurricanes have experienced significant damage exposing the occupants and the building envelope to uncomfortable and dangerous conditions. A new approach to the design of ... -
High strain properties of advanced high strength spot welded steels
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This research was conducted to investigate and characterize the high strain rate compressive loading behavior of DP600 GI, an advanced high strength ... -
An investigation of nonlinear tip-sample force models for nanoindentation
(University of Missouri--Columbia, 2007)Current physical models of tip-sample interactions in nanoindentation and atomic force microscopy are exclusively based on either the Johnson-Kendall-Roberts (JKR) or Derjaguin-Muller-Toporov (DMT) models of adhesive contact ... -
Nonlinear control and active damping of a forced-feedback metering poppet valve
(University of Missouri--Columbia, 2007)For a metering poppet valve which was developed at the University of Missouri (MU valve), the valve can be configured for performance at the cost of stability. It is desirable to achieve both performance and stability using ... -
Parametric and optimal design of modular machine tools
(University of Missouri--Columbia, 2007)Over the years machine tools for manufacturing have developed into two classes. One is the general purpose machine tools, and the other is designed for machining large quantities of a specific part or process. These ...
