Available in PDF, EPUB and Kindle. Book excerpt: The effect of shear stress on the magnitude and directional variation of the dynamic bulk modulus of sand was investigated by means of a program of laboratory measurements of P-wave and S-wave velocities under varied stress conditions. The sand used was air-dry Reid-Bedford Model sand and was tested at relative densities of about 25% and 80%. Test specimens were 4 ft high by 4 ft in diameter, formed by pluviation in air a cylindrical pressure chamber. The test results indicate that compression and shear wave velocities vary with direction in an isotropic stress field due to inherent anisotropy of the sand structure, but that this phenomenon has only a modest (0-20%) effect in producing anisotropy in the bulk modulus. The work tends to confirm, within + or - 10%, that the shear wave velocity depends only on the level of octahedral normal effective stress and not on stress anisotropy. IN contrast with the shear wave velocity, the compression wave velocity increases significantly in the direction of the major principal stress and depends primarily on the effective stress on the plane normal to wave travel. Values of bulk modulus, computed from the wave velocities under the assumption of elastic isotropy, show a variation with direction, which contradicts the assumption of isotropy. Appendix A contains photographs of typical oscilloscope waveforms from each replicate series of five impacts, and Appendix B presents tables of corrected Vp and Vs, the push wave and shear wave velocities, respectively, from each test.

Available in PDF, EPUB and Kindle. Book excerpt: Shear waves and closely related interface waves (Rayleigh, Stoneley and Scholte) play an important role in many areas of engineering, geophysics and underwater acoustics. In some cases interest is focused on large-amplitude waves of low frequency such as those associ ated with earthquakes and nuclear explosions; in other cases low amplitude waves, which have often travelled great distances through the sediment, are of interest. Both low and high frequency shear and interface waves are often used for seafloor probing and sediment characterization. As a result of the wide spectrum of different interests, different disciplines have developed lines of research and a literature particularly suited to their own problems. For example water-column acousticians view the seafloor sediment as the lower boundary of their domain and are interested in shear and interface waves in the near bottom sediments mainly from the standpoint of how they influence absorption and reflection at this boundary. On the other hand, geophysicists seeking deep oil deposits are interested in the maximum penetration into the sediments and the tell-tale characteristics of the seismic waves that have encountered potential oil or gas bearing strata. In another area, geotechnical engineers use shear and interface waves to study soil properties necessary for the design and the siting of seafloor structures.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.
