This book was released on 1976 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a series of two-dimensional plane-strain, dynamic finite element, structure-medium interaction code calculations are presented. These calculations parametrically investigated the effect of variations in constitutive properties of the backfill region around a hypothetical, shallow-buried protective structure. Two parameter studies were conducted on this plane-strain idealization of a simple buried structure while under a long duration local surface air-blast loading: The first investigated differences in the dynamic response of the structure under this loading due to changing the surrounding backfill from a dense (or well-compacted) glacial till to the same material in a loose (or poorly compacted) condition; The second is identical with the first except that dense and loose clay shale materials were simulated. The calculations indicated that, for the particular idealized problem investigated, the use of loose rather than dense backfill results in (1) increased deflections across backfill sections; (2) increased loads on, deflections of, and thrusts, shears, and bending moments within the structure, and (3) increased amplitudes of the shock spectra for points on the inside surface of the structure.
