Identifying customer requirements and designing for modularity in developing specialized, low production volume products

Creator:: van Tamelen, Peter G.
Abstract:: Field biologists are in need of more specialized and technical equipment than they are able to produce on their own in order to collect data more efficiently or gather data that is not currently available. This presents a challenge for design engineers because these products are typically highly specialized and...

Heat treatment characteristics of heavily doped epitaxial silicon materials

Creator:: Wijaranakula, Witawat
Abstract:: Nucleation and growth kinetics of oxygen precipitates and bulk defects in epitaxial silicon wafers were investigated. Low temperature nucleation heat treatments were applied to the well characterized epitaxial silicon wafers before and after the epitaxial deposition processing. Subsequently the wafers were heat treated at a high temperature. In the case...

Biaxial fatigue behavior of commercially pure titanium Ti-50A (Grade 2) and low-alloy titanium Ti-Code 12 (Grade 12) heat exchanger materials

Creator:: Tobias, Benjamin C.
Abstract:: Material failures in heat exchangers are often closely tied to events associated with the conditions of service and operating parameters. These events can generally be attributed to adverse load application and higher than optimum operating temperatures that could lead to changes in the microstructure of the materials and fatigue failure...

Design, analysis, and validation of composite c-channel beams

Creator:: Koski, William C.
Abstract:: A lightweight carbon fiber reinforced polymer (CFRP) c-channel beam was previously designed using analytical theory and finite element analysis and subsequently manufactured through a pultrusion process. Physical testing revealed the prototype did not meet the bending and torsional stiffness of the beam model. An investigation revealed that the manufactured prototype...

A study of compression loading of composite laminates

Creator:: Berbinau, Pierre J.
Abstract:: The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

Simulating Soot Formation and Growth using a Parallel Coupled Monte Carlo Method

Creator:: Peters, Jordan
Abstract:: Small hydrocarbon particles such as soot and soot precursors pose a serious threat to human health and Earth's climate. Understanding the mechanisms by which soot particles form and grow is the first step to reducing the prevalence of these particles. Computational simulations are used to investigate combusting systems which are...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

Creator:: Lovejoy, Steven C.
Abstract:: A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...
