  • Functional Materials and Techniques for Additive Manufacturing in Soft Robotics

    Creator:
    Walker, Stephanie
    Abstract:
    This thesis outlines the development of new elastomeric materials and manufacturing processes for soft robotics. Specifically, this work describes the development of custom material formulations for use in additive manufacturing, additive manufacturing processing techniques for silicone elastomers, and multi-component additive manufacturing techniques. Material synthesis and processing is a gap in...

  • Direct 3D Printing of Silicone Elastomer Soft Robots without Support

    Creator:
    Morrow, John F.
    Abstract:
    Soft robotics utilizes compliant materials (such as rubber) to make robots that are flexible and safe around humans, however these materials present many practical manufacturing challenges. Current fabrication methods use molding techniques which limits the soft robot designs which could be fabricated and impacts part consistency. This defense introduces a...

  • Effect of Laser Powder Bed Fusion Parameters and Hot Isostatic Pressing on the Microstructure and Mechanical Properties of C22 Alloy

    Creator:
    Yan, Dongqing
    Abstract:
    A nickel-based Hastelloy C22 powder with a nominal composition of Ni-21.30Cr-13.36Mo-1.92Co-2.94W-3.85Fe-0.23Mn-0.3V(wt%) and particle size distribution of D₁₀=23.8±0.3 μm, D₅₀=37.5±0.2μm, and D₉₀=59.3±1.1 μm was gas atomized to be used as a feedstock in Laser Powder Bed Fusion (LPBF). In this study, laser power and scanning speed were optimized to manufacture specimens...

  • Wave Energy Converter Array Optimization : Array Economic Analysis and Preliminary Results of a Genetic Algorithm Approach Introducing Cost Factors

    Creator:
    Sharp, Christopher J.
    Abstract:
    With the need to integrate renewable energy sources into the current energy portfolio and the proximity of many population centers to an ocean coastline, it is pressing that marine energy systems, specifically wave energy converters (WECs), are evaluated as potential solutions for meeting energy needs. In order to best understand...

  • A comparison of single runs versus multistart for simulated annealing and threshold accepting

    Creator:
    Crews, Matthew
    Abstract:
    Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...

  • An investigation into the electrochemical removal of unwanted residual material protrusions from parts

    Creator:
    Bingham, Bruce C.
    Abstract:
    Manuscript I: The removal of residual casting material from gating has traditionally been performed by abrasive grinding techniques. However, high amounts of belt wear can occur when working with high strength alloys, especially those typically seen in the aerospace industry. An alternative machining process called electrochemical machining (ECM) uses electrolysis...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • Mining Temporal Patterns for Prediction: A Mixed-Integer Programming Approach

    Creator:
    Mansourifard, Farzaneh
    Abstract:
    In the past two decades, the advancement in data collection and storage have led to the accumulation of complex datasets. Consequently, various industries have sought data-driven solutions to predict and detect anomalies. Temporal patterns have emerged as potential features in prediction models that could improve the performance of the identification...

    Bozorgirad, Mir Abbas
    Abstract:
    In this research, a bi-criteria group scheduling problem is investigated in hybrid flow shop (HFS) environments, where the parallel machines in each stage are unrelated, meaning not identical. The objective of the problem is to minimize a linear combination of the total weighted completion times as a means of complying...
