  • High cycle fatigue modeling and analysis for deck floor truss connection details

    Creator:
    DePiero, Anthony H.
    Abstract:
    The Oregon Department of Transportation is responsible for many steel deck truss bridges containing connection details that are fatigue prone. A typical bridge, the Winchester Bridge in Roseburg, Oregon, was analyzed to assess the loading conditions, stress levels, and fatigue life of the connection details. The analysis included linear-elastic beam...

  • Analysis, testing, and redesign of an environmental control system for an engine dynamometer

    Creator:
    Morris, Taylor H.
    Abstract:
    This project analyzes, tests, and redesigns an environmental control system for Global Formula Racing’s (GFR) dynamometer. It seeks to develop a working system to test GFR’s car engine under air conditions similar to those faced during competition. A model is developed to predict the performance of the environmental control system,...

  • Design of an automated system for imaging and sorting soil mesofauna

    Creator:
    Chamblin, Mike A.
    Abstract:
    Identification and population counts of soil mesofauna can be an important tool for soil ecologists to determine the soil biodiversity. Information provided from population counts can give insight to soil ecologists about the effects of human land use, monitoring soil and water health, benefits of soil biodiversity in agriculture, and...

  • The wave energy resource of the US Pacific Northwest

    Creator:
    Lenee-Bluhm, Pukha
    Abstract:
    The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...

  • Influence of subset size, shape and orientation on texture based digital image correlation

    Creator:
    Cui, Jianqing
    Abstract:
    Digital Image Correlation(DIC) is one of full-field strain measurement techniques devel- oped in recent decades, which has been well-demonstrated to conduct the mechanical properties study of solid materials, by collecting data using digital cameras. X-ray to- mography(CT) imaging helps the correlation techniques expanded to three dimensional investigation of materials, known...

  • Knowing your customers : ontological gathering and analysis techniques

    Creator:
    Nix, Anthony A.
    Abstract:
    This research presents a methodology to analyze customer needs and direct the gathering of customer needs that both span the need space and are independent. An ontological categorization, the fundamental research contribution of this work, is created to support both aims of the overall methodology. Providing designers with a customer...

  • Customer needs elicitation and disability simulation suit validation to benefit knowledge and methods for inclusive product design

    Creator:
    Armstrong, Jessica
    Abstract:
    Current product design methodologies are not conducive to creating inclusive products (products that meet the needs of persons with and without disabilities). In order to reduce the effort and expense involved in creating inclusive products, empathic design principles are applied to discover whether customer needs for people with disabilities can...

  • Effect of lateral force on passenger comfort during a mechanically assisteddependent transfer

    Creator:
    Mast, Jonathan J.
    Abstract:
    Air travel presents several problems for passengers with disabilities. One in particular is how they get from their wheelchair and to an aircraft seat. The commonly used manual transfer method is hazardous to the assistants and the passenger. There are other alternatives, but they have plenty of room for improvement....

  • Failure analysis of pre-notched composite laminated plates under four-point bending conditions

    Creator:
    Arias Gonzales, Sergio
    Abstract:
    Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...

  • Distortion-induced fatigue cracking of girder-to-crossbeam connection

    Creator:
    Aljutaili, Dhari S.
    Abstract:
    Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...
