  • Experimental Classification of Intralaminar Matrix Compression Damage Propagation in Carbon Fiber Reinforced Polymers

    Creator:
    Daniels, Mitchell Alan
    Abstract:
    Composites often are able to carry more load after damage due to the structure of laminates. In addition, damage can be difficult to detect in composites compared to homogeneous materials. Understanding the behavior of composite material after damage is vital for composite structural design. Currently, experimental methods exist for classifying...

  • Learning approaches for the early detection of kickback in chainsaws

    Creator:
    Arnold, Drew D.
    Abstract:
    Among the many safety hazards facing chainsaw operators, the phenomenon known as kickback is the most dangerous. Kickback occurs when the chain at the tip of the chainsaw is caused to stop abruptly, and transfers the energy of the cutting chain to motion of the saw. The saw will rotate...

  • A Free Running Lubrication Comparison of Commonly Used Bar and Chain Oil

    Creator:
    Orawiec, Alexander
    Abstract:
    Chain saws are a common tool used by large logging corporations and family homesteads to manage forests, limb trees and buck lumber. A significant cost of operation is the continuous required supply of bar and chain oil. Consumers and logging corporations desire a lubricant with a high performance to cost...

  • 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...

  • Determination of cohesive parameters for aerospace adhesives

    Creator:
    Hortnagl, Josef G.
    Abstract:
    The use of adhesives in demanding engineering applications is a very common occurrence in the modern world. These adhesives are taking the role of many traditional fasteners, especially in the area of fiber reinforced composites. As the use of these adhesives become more common place, better understanding of their mechanics...

  • Determination of cutting forces with asymmetric wedged blades

    Creator:
    Phan, Andrew Vinh
    Abstract:
    Cutting operations using blades appear in several different industries such as food processing, surgical operations, gardening equipment, and so forth. As our society continues to increase our technological prowess, there is an ongoing need to better understand the underlying causes of simple tasks such as cutting so that cutting operations...

  • Effects of nickel addition In Cu-Zr-Hf-Al metallic glass matrix

    Creator:
    Miska, John
    Abstract:
    Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...

  • Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

    Creator:
    Yarger, David J.
    Abstract:
    Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

  • Post-Preservation Maintenance of Cadavers to Prevent Tissue-Dehydration in Educational Environments

    Creator:
    Herrera, Alexandria R.
    Abstract:
    In anatomical education, clinicians, surgeons, and anatomists support the use of human cadavers over digital or artificial alternatives. Cadaver use raises the challenge of preventing tissue dehydration. The OSU cadaver labs attempt to maintain hydration by re-covering the exposed tissues with original skin, layers of plastic wrap, and/or towels and...

    Creator:
    Ray, Cody W.
    Abstract:
    Engineers have long been inspired by nature's flyers. Such animals navigate complex environments gracefully and efficiently by using a variety of evolutionary adaptations for high-performance flight. Biologists have discovered a variety of sensory adaptations that provide flow state feedback and allow flying animals to feel their way through flight. A...
