This book was released on 1963 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains a critical review of the literature on the dynamic testing of soils. The review was conducted prior to the design of an apparatus for dynamic direct shear tests. The specifications for the apparatus generated from this review and the preliminary design of the apparatus are presented. Included are appendixes containing annotated bibliographies (421 entries) on soil dynamics, stress-wave propagation, and nuclear and high-explosive cratering. (Author).

Download or read book Computation by the Method of Characteristics of Disturbance in an Elastic Half space Caused by Blast like Surface Loading written by Clarence Maurice Ablow and published by . This book was released on 1967 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The computation by the method of characteristics developed in this report locates propagating shocks and gives thier strengths precisely. It can provide the other details of the disturbance field with arbitrary accuracy through refinement of the finite difference mesh. Since the equations represent a medium without dissipation, their stabilization is a major difficulty. This stability problem has not yet been solved completely so that no numerical results of engineering usefulness are presented. The continuation and completion of the development of the present exact calculation method is recommended so that results of simpler, approximate methods for non-elastic media can be checked.

This book was released on 1973 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses vertical airblast-induced ground motions produced by nuclear explosions over a dry soil medium taken to model Frenchman Flat of the Nevada Test Site (NTS). Material properties for use in first principle calculations were synthesized from very limited dynamic laboratory stress-strain data, various soil index characteristics, and seismic data. Parametric calculations with a one-dimensional, plane-strain finite difference code were used to define a theoretical simplified model that expresses peak vertical particle velocities and displacements as a function of yield, peak overpressure and depth. Ground motions predicted by this model were then compared to ground motion data from nuclear explosions in Frenchman Flat. In particular, predictions of the simplified model were reasonably consistent with PRISCILLA data which were a primary basis of empirical prediction procedures widely used in the design and analysis of strategic structures during the past ten years. The theoretical model could be altered (where little or no dynamic soil property data exist) to provide even better agreement between calculated and measured ground motions. Conversely, study of qualitative features of the theoretical results provide insight into the basic wave propagation phenomena in Frenchman Flat that could improve the interpretation of the experimental data such that a more consistent comparison between theory and experiment may result.

Available in PDF, EPUB and Kindle. Book excerpt: Free-field ground motions for use in the design of underground protective structures are studied. Two-dimensional motion of an elastic half-plane under an exponentially decaying normal load traveling at constant velocity along the boundary is determined analytically and the results are presented graphically. Analytic expressions in integral form are obtained for three-dimensional axisymmetric motion of an initially quiescent homogeneous isotropic elastic half-space underAN ARBITRARY AXISYMMETRIC TIME-DEPENDENT NORMAL LOADING, AND THESE EXPRESSIONS ARE UTILIZED FOR THE SPECIAL CASES OF A CONCENTRATED NORMAL POINT LOAD AND A UNIFORM CONCENTRATED NORMAL RING LOAD SUDDENLY APPLIED AND THEREAFTER MAINTAINED AT A FIXED POSITION ON THE PLANE BOUNDARY. Analytic expressions in integral form are obtained for the three-dimensional axisymmetric motion of a homogeneous isotropic visco-elastic half-space under identical conditions as for the elastic case.

This book was released on 1984 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a continuing investigation of the characteristics of the low frequency ground motions produced by atmospheric explosions. The studies reported here have focused on two aspects of this problem: (1) the full-scale validation of nuclear tests, and (2) the preliminary evaluation of a theoretically-based prediction methodology. With regard to the validation study, the mathematical model has been applied to the theoretical simulation of ground motion data recorded from the Nevada Test Site atmospheric nuclear explosions TUMBLER I, UPSHOT-KNOTHOLE 10 and SMALL BOY. The results of these simulations have confirmed the fact that the observed low frequency ground motions from such explosions can be accounted for by the airblast-induced, elastic surface waves. Moreover, the simulation analysis of the ground motion data recorded from the near-surface SMALL BOY explosion has confirmed the existence of an 'exclusion radius' for such events, within which incident airblast energy is not efficiently coupled into the surface wave mode of propagation due to dissipation associated with strong, nonlinear interaction effects. On the other hand, the evidence provided by the TUMBLER I and UPSHOT-KNOTHOLE 10 analyses has indicated that this exclusion radius is effectively zero for explosions with significant height of burst.
