  • Usage of Digital Image Correlation in Single and Multiple Stereo Systems for Strain and Shape Measurement

    Creator:
    McKinley, Timothy A.
    Abstract:
    This dissertation details the application of digital image correlation (DIC) in novel methods for mechanical testing and shape characterization. The first usage manifested in the development of a novel composite test specimen that provided the ability to characterize the matrix compression energy release rate at initiation and subsequent crack propagation....

  • In-Situ Stereo Vision Metrology for Metal Powder Bed Fusion Additive Manufacturing

    Creator:
    Mosher, Daniel P.
    Abstract:
    Powder Bed Fusion (PBF) techniques are additive manufacturing (AM) technologies with paradigm-shifting potential for the production industry. However, before they can become viable production solutions for quality critical industries, issues with process consistency and repeatability need to be addressed. There is a need for in-situ sensing systems that characterize process...

  • Mechanical Behavior of Elastomer Polymer under Shear and Compression: Experimental Investigation Using Digital Image Correlation

    Creator:
    Raheem, Hassan M.
    Abstract:
    Due to their viscoelastic properties, polymers and hydrogels are widely used in many applications. In this study, the viscoelastic properties of elastomer polymers were investigated for a series of hydrogel, hydrogel composites and silicon materials. A primary application for hydrogels and hydrogel composites is as a replacement for the degenerated...

  • Modeling, control, and estimation of flexible, aerodynamic structures

    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...

  • 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,...

  • Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

    Creator:
    Taie, Zachary
    Abstract:
    There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

  • Incremental Forming of Polymers at Room Temperature

    Creator:
    Davar Panah, Mohammad Ali
    Abstract:
    Single Point Incremental Forming (SPIF) is a forming process in which a fully clamped sheet is formed by a hemispherical ended tool that moves along a predefined 3D toolpath. The sheet is formed in a series of local deformations to reach its desired shape. Double Sided Incremental Forming (DSIF) includes...

  • Bio-Inspired Design of Vehicles that Operate in Complex Environments

    Creator:
    Jackson, Danielle M.
    Abstract:
    This dissertation focuses on defining underlying mechanisms to enable the bio-inspired design of aerodynamic and/or hydrodynamic vehicles that operate within complex environments. This dissertation introduces four overarching research gaps found in current bio-inspired design research and four corresponding approach questions that guide the framework of the presented research. This research...

  • Topological Design Considering Uncertainty and Hyperelasticity

    Creator:
    Pham, Trung
    Abstract:
    Topology optimization (TO) is a mathematical method to find the optimal size, shape and connectivity of a domain under specified conditions, and has had many applications in engineering design. However, challenges remain in realizing TO as an effective design tool for many design situations. Uncertainty is ubiquitous in nature and...

  • Further Development of MPM and its Applications in Modeling Wood-Adhesive Bonds

    Creator:
    Hammerquist, Chad C.
    Abstract:
    This work is a culmination of a series of published works related to the use of the Material Point Method (MPM) in modeling wood adhesive bonds. The use of wood as construction material has the potential to play a small role in the solution to the current CO2 and climate...
