Available in PDF, EPUB and Kindle. Book excerpt: Specimens of clayey soils with a controlled pore solution chemistry were prepared, consolidated, and equilibrated at three different soil suction levels. Some specimens were subjected to creep/recovery tests in conventional triaxial cells. These results were used to select viscoelastic models that could explain the specimen behavior. Duplicate specimens equilibrated at the same soil suction levels were tested in a dynamic triaxial test system. For this purpose, the specimen was subjected to a series of stress controlled pulses of 50msec duration and consisting of a ramp-up to a peak deviatoric stress and a ramp-down to zero. The peak stress was increased for successive pulses. The response of the specimen, and the strain-time history, was then recorded. The non-linear viscoelastic models fitted to creep-recovery tests were used in combination with the modified superposition principle to predict the expected response of the specimen. The viscoelastic models that were fitted to the steady creep phase did not provide the best match. It was rather necessary to use the models fitted to the initial part of the transient creep phase ... Creep, High strain rates, Unsaturated clayey soils.

Available in PDF, EPUB and Kindle. Book excerpt: The Split-Hopkinson Pressure Bar was used to study the uniaxial stress-strain behavior of compacted moist soils under one-dimensional, undrained, confined compression loading at high strain rates (1000/sec and 2000/ sec. Three soils, Eglin Sand, Tyndall sand and Ottawa 20-20 sand were tested. The results suggest that the stress strain response is dominated by the water- phase from the lock-up strain and beyond. The soil skeleton dominates the response from the start of loading up to the lock-up strain. It appears that there may be some strain-rate effects, however, the data arc insufficient to adequately demonstrate this and further investigation is suggested. The research described in this report has demonstrated that the Split-Hopkinson Bar System is a viable technique for high strain rate dynamic geotechnical testing of unsaturated, saturated, and dry soils, and provides a framework for conducting further studies.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: In recent decades the development of unsaturated soil mechanics has been remarkable, resulting in momentous advances in fundamental knowledge, testing techniques, computational procedures, prediction methodologies and geotechnical practice. The advances have spanned the full spectrum of theory and practice. In addition, unsaturated materials exhibiting complex behaviour such as residual soils, swelling soils, compacted soils, collapsing soils, tropical soils and solid wastes have been integrated in a common understanding of shared behaviour features. It is also noteworthy that unsaturated soil mechanics has proved surprisingly fruitful in expanding to other neighbouring areas such as swelling rocks, rockfill mechanics, and freezing soils. As a consequence, geotechnical engineering involving unsaturated soils can be now approached from a more rational and systematic perspective leading towards an improved and more effective practice. Unsaturated Soils contains the papers presented at the 5th International Conference on Unsaturated Soil (Barcelona, Spain, 6-8 September 2010). They report significant advances in the areas of unsaturated soil behaviour, testing techniques, constitutive and numerical modelling and applications. The areas of application include soil-atmosphere interaction, foundations, slopes, embankments, pavements, geoenviromental problems and emerging topics. They are complemented by three keynote lectures and three general reports covering general issues of modelling, testing and applications. Unsaturated Soils is a comprehensive record of the state-of-the art in unsaturated soil mechanics and a sound basis for further progress in the future. The two volumes will serve as an essential reference for academics, researchers and practitioners interested in unsaturated soils.

Download or read book Shock Phenomena in Granular and Porous Materials written by Tracy J. Vogler and published by Springer Nature. This book was released on 2019-09-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Granular forms of common materials such as metals and ceramics, sands and soils, porous energetic materials (explosives, reactive mixtures), and foams exhibit interesting behaviors due to their heterogeneity and critical length scale, typically commensurate with the grain or pore size. Under extreme conditions of impact, granular and porous materials display highly localized phenomena such as fracture, inelastic deformation, and the closure of voids, which in turn strongly influence the bulk response. Due to the complex nature of these interactions and the short time scales involved, computational methods have proven to be powerful tools to investigate these phenomena. Thus, the coupled use of experiment, theory, and simulation is critical to advancing our understanding of shock processes in initially porous and granular materials. This is a comprehensive volume on granular and porous materials for researchers working in the area of shock and impact physics. The book is divided into three sections, where the first presents the fundamentals of shock physics as it pertains to the equation of state, compaction, and strength properties of porous materials. Building on these fundamentals, the next section examines several applications where dynamic processes involving initially porous materials are prevalent, focusing on the areas of penetration, planetary impact, and reactive munitions. The final section provides a look at emerging areas in the field, where the expansion of experimental and computational capabilities are opening the door for new opportunities in the areas of advanced light sources, molecular dynamics modeling, and additively manufactured porous structures. By intermixing experiment, theory, and simulation throughout, this book serves as an excellent, up-to-date desk reference for those in the field of shock compression science of porous and granular materials.
