New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

More information is available at Theses and Dissertations at University of Maryland Libraries.

    Mitigation of Acceleration of Vehicles Subjected to Buried Mine Loading
    (2015) Plitt, Zachary Tyler; Fourney, William; Mechanical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation investigates the mitigation of acceleration to passengers on a blast loaded vehicle. Small scale explosive testing was conducted to simulate the detonation of a buried mine on a vehicle. Tests were conducted in saturated sand, which will act as the loading mechanism on the simulated vehicle. Piezoelectric accelerometers, in conjunction with high speed cameras, were used to record test data. Two forms of mitigation were utilized in this research: hull shaping and crushing polyurea-coated thin-walled cylinders. Hull shaping deflects the blast, while the polyurea-coated thin-walled cylinders are crushed to absorb energy. Both forms of mitigation were tested, both separately and together, to determine their effectiveness at mitigating acceleration on the simulated vehicle. The goal of this dissertation is to determine the effectiveness of different mitigation techniques at reducing acceleration in order to design safer military vehicles.
