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 give thesis/dissertation in DRUM

    Vehicle Shaping for Mine Blast Damage Reduction
    (2006-07-28) Genson, Kevin William; Fourney, William; Mechanical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    When a buried explosive is detonated beneath a target (such as a vehicle), the target is rapidly loaded by flying ejecta, high pressure gas, and shock waves. This paper explores how changes in the shape of the underside of a target affect the total impulse captured from the detonation of a buried charge. The effects of changes in target height and charge burial depth are also examined. Testing was conducted on dihedral target plates using 0.636 gram charges. These were buried in saturated sand at three depths, and shaped targets were placed at four heights above the surface. The impulse applied to the plate by the exploding charge was determined through analysis of high speed digital video recordings. Changing the geometry of the target reduced the impulse by up to 45%. Increasing standoff distance reduced impulse by up to 70%.
