This book was released on 1964 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general approach, physical concepts, and methods employed in the actual development of the equipment are discussed. The equipment and its capabilities are described. A brief summary of concurrent reports that describe results of studies of response in granular media is presented. The summary indicates that the significant parameters have been correctly identified from theoretical mechanics and suitably measured, since results demonstrate relationships between stress-strain behavior and propagating waves in laboratory devices. The report also summarizes the broad range of protective construction problems which lend themselves to study in this equipment. These include such studies as the effects of reflection phenomena, the effects of layered media, soil-structure interaction in a high-stress field, and the evaluation of disturbances in free-field conditions caused by the presence of a gauge. The latter is shown to be possible by virtue of the ability to measure soil response without placing a gauge in the soil or attaching one to the sample. (Author).

This book was released on 1968 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general-purpose test facility for determining the one-dimensional compression characteristics of soils subjected to impulse-type loads has been developed in order to help satisfy the ever-increasing demand for reliable soil-property data required in support of a wide variety of nuclear-weapons-effects-related problems. The design, fabrication, installation, and evaluation of the various elements which together comprise the test facility were accomplished. The various considerations involved in the design and evaluation of the newly developed test facility are discussed in detail, thus providing some insight into the types of factors which affect the experimental-accuracy capability of a one-dimensional compression test facility and thereby the reliability of the data obtained under any particular set of conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study was to investigate and verify model-to-prototype scaling relations for blast loaded buried arches that respond both elastically and inelastically. Four geometrically similar, semicircular aluminum alloy arches with 4-, 8-, 12-, and 36-inch diameters were buried in dense dry sand and subjected to air-blast-induced loads on the surface. The tests were conducted at the Large Blast Load Generator located at the U.S. Army Engineer Waterways Experiment Station. The results of two series of tests, each consisting of 3 repeated shots, ranging from 70 to 300 psi, are presented. Within the range of parameters investigated, the scaling of the dependent variables were adequately verified. These variables included acceleration, velocity, displacement, thrust, and bending moment. (Author).

This book was released on 1967 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a definitive experimental study in which shock-induced square-wave pulses in soil were observed to give way to decaying pulse shapes, as in a gas shock tube, and rapid attenuation of peak stress occurred thereafter due to nonlinear propagation in the rarefaction. In the study three different duration pulses were applied to an 8-ft vertical column of granular material confined under boundary conditions leading to a stress-strain (Sigma - Epsilon) behavior described by d to the 2nd power Sigma/d Epsilon to the 2nd power> 0, i.e., a strain-hardening type of response. Applied stresses ranged from 50 to 500 psi. The report describes a simple modification to be applied to the prediction procedure described in the first report of this series in order to take into account, to a first approximation, the nonlinear propagation of unloading waves that occurs in real media because of nonlinear stress-strain behavior in the unloading branch. The procedure which predicts stress and motion histories based on the conservation laws, a measured constitutive relationship, and the applied pressure-time profile, is demonstrated by predicting the entire sequence of an experimentally observed square-wave pulse transformation into a decaying pulse.

Book excerpt: Sponsored by the Executive Committee of the Geotechnical Engineering Division of ASCE. This Geotechnical Special Publication contains eight lectures given between 1974 and 1983 in honor of Karl Terzaghi and repressenting diverse aspects of geotechnical engineering and engineering geology. Topics include: the relationship of geology and geotechnical engineering and how a study of the geology of engineering sites is an important starting point for all geotechnical site studies; effects of dynamic soil properties on soil-structure interaction; bearing capacity and settlement of pile foundations; design and construction of drilled shafts; evaluating calculated risk in geotechnical engineering; proposal forØthe establishment of a national center for investigating civil engineering failures, with several case studies; pre-Columbian earth construction in the Americas and technological developments between 2,500 and 500 years ago; and recent progress in the design and construction of concrete-face rockfill dams. The 1978 lecture by the late N.M. Newmark is not included.
