Analysis and modeling of direct selective laser sintering of two-component metal powders
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Direct Selective Laser Sintering (SLS) is an emerging technology of Solid Freeform Fabrication (SFF) that 3-D parts are built from the metal-based ...
Blackbody temperature calculations from visible and newa-IR spectra for gas-fired furnaces
(University of Missouri--Columbia, 2005)
The goal of this research work is to develop a system capable of measuring multiple factors of interest in the operation of gas-fired furnaces. The primary focus is the development of a model for calculating wall or flame ...
A generalized approach for calculation of the eigenvector sensitivity for various eigenvector normalizations
(University of Missouri--Columbia, 2005)
Sensitivity analysis is an important step in any gradient based optimization problem. Eigenvalue and Eigenvector Sensitivity Analysis has been a major area for more than three decades in structural optimization. An efficient ...
Mechanical and thermal buckling of thin films
(University of Missouri--Columbia, 2005)
Devices with feature size on the order of one micrometer have found widespread applications in science and engineering. MEMS, is a rapidly growing technology for the fabrication of miniature devices which provides a way ...
Analysis of heat transfer in subcooled metal powder subjected to pulsed laser heating
(University of Missouri--Columbia, 2005)
The interaction of metal powder and pulsed laser heat flux is investigated on two levels, the powder bed level and the particle level. The locations of the thermal penetration depth and the liquid-solid interface are ...
Comprehensive optimization for thermoelectric refrigeration devices
(University of Missouri--Columbia, 2005)
A large market is currently in place for which thermoelectric (TE) technology can provide diverse energy solutions. This market should continue to grow as improvements are made to TE materials. In the last 10-15 years, ...
X-ray topography techniques for the analysis of laser irradiated silicon
(University of Missouri--Columbia, 2005)
There is currently much interest in femtosecond scale laser interactions with materials. Comparison of the damage produced by the femtosecond laser pulses to the longer laser pulses is also of interest. This study examined ...
Neutron diffraction study of load response and residual stresses in WC-(Ni/Co) composites
(University of Missouri--Columbia, 2005)
The in-situ response of WC-Ni and WC-Co composites under compressive loading was measured using neutron diffraction techniques. These measurements give a clear indication of the elastic strain behavior of both the carbide ...
Exploratory development of VARIM process for manufacturing high temperature polymer matrix composites
(University of Missouri--Columbia, 2005)
This research focuses on an exploratory development of vacuum assisted resin infusion molding (VARIM) process for manufacturing high temperature polymer composite materials. High temperature matrix composites are needed ...
Finite element analysis of residual stress generation during spot welding and its affect on fatigue behavior of spot welded joints
(University of Missouri--Columbia, 2005)
This dissertation presents the finite element based prediction of residual stress generation in a spot welded joint during the spot welding process and the effects of residual stress on fatigue behavior of a spot welded ...
Development of an integrated approach combining artificial neural network material based on modeling with finite element analysis of forming processes
(University of Missouri--Columbia, 2005)
The use of a finite element model for design and analysis of a metal forming processes is limited by the incorporated material model's ability to predict deformation behavior over a wide range of operating conditions. ...
