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%. 7652162 bytes application/pdf en_US Vehicle Shaping for Mine Blast Damage Reduction Thesis Engineering, Mechanical buried charge vehicle mine landmine dynamic effect small scale testing explosive mine blast standoff distance target geometry design armored vehicle blast scaling hopkinson armor military blast effect open.access
