This book was released on 2012-12-06 with total page 411 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 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought 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 con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration 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 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2001 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the effect of compaction methods on soil swell pressure, unconfined compressive strength, and swell potential of three types of soils in Jordan. Undisturbed and disturbed soil samples were collected from the field and used for this study. Compacted soil specimens were prepared using dynamic compaction, static compaction, and kneading compaction. Swell potential test, swelling pressure test, and unconfined compression test were conducted on identical samples compacted by different methods, and having similar initial conditions to the undisturbed samples. Other sets of experiments were also conducted to examine the influence of initial water content on swell pressure and unconfined compressive strength under different compaction techniques. Results indicated that the undisturbed samples have the highest swelling pressure and swell potential values followed by dynamic compaction, while kneading compaction gave the lowest values for the three soils. For the same soil, it has been found that the swelling pressures of the undisturbed samples were 1.5, 1.96, and 3.07 times of that for the dynamic, static, and kneading compaction, respectively. Similar trends were obtained with regard to unconfined compressive strength and swell potential. The unconfined compressive strengths of the undisturbed samples were 1.35, 1.6, and 2.53 times higher than that of the soil specimen compacted according to the dynamic, static, and kneading procedures, respectively.

This book was released on 1960 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: The measurement of negative pore water pressures in soil systems is important in both research and design studies on precompressed saturated clays and partially saturated compacted clays. Paper 2: The mechanisms believed to cause swelling in saturated clay-water systems are first reviewed. Test data are presented to show the effects of the ion concentration in the pore fluid on the swelling behavior of a highly plastic clay. Paper 3: The results of a laboratory investigation are reported of the effects of rate of strain on the strength of remolded soil.

This book was released on 2016 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clays are used widely in sanitary landfills, embankment dams, highway embankments, hydraulic barriers, and foundations. In most of these applications, clays are compacted at maximum dry density (MDD) and optimum water content (OWC). Density and water content have a profound effect on the strength and deformation behavior of compacted clays. However, this effect has not been quantified in detail, especially the water content at which transition from brittle to plastic behavior occurs for low, medium, and high plasticity clays. The objective of this research was to investigate the effect of varying water content and density on the strength and deformation behavior of low, medium, and high plasticity clays, and to quantify the transition water content between brittle and plastic behavior for each type of clay. Initially, six samples each of low, medium, and high plasticity clays were compacted, three on the dry side and three on the wet side of OWC, to establish their compaction curves. The compacted samples were failed axially under unconfined compression and were visually inspected to determine the water content at which transition occurred between brittle and plastic deformation. Additionally, three samples of each type of clay were compacted at different water contents and failed using the direct shear test. The stress-strain curves from both tests were used to determine the transition water content between brittle and plastic behaviors. The MDD values for low, medium, and high plasticity clays were found to be 102.5 lb/ft3 (1.64 Mg/m3), 95 lb/ft3 (1.52 Mg/m3), and 89.5 lb/ft3 (1.43 Mg/m3), with the corresponding OWC values of 18%, 25%, and 27%, respectively. The compressive strength values for the low, medium, and high plasticity clays at MDD and OWC were 54 psi (344.8 kPa), 59 psi (413.8 kPa), and 60 psi (420.7 kPa), respectively. The unconfined compressive strength first increased and then decreased with increasing water content, with the change in trend occurring within 5% of OWC for each type of clay. The high plasticity clay had the highest cohesion while the low plasticity clay had the highest friction angle. The transition between brittle and plastic behavior for the low, medium, and high plasticity clays occurred between 19-20%, 27-29%, and 30-32% water content, respectively. This study was aimed at determining the transition water content as it relates to both brittle and plastic deformation. Earthquakes can cause failure of embankment dams in the form of cracking due to displacements or differential settlements from the vibrations. To prevent such failures from occurring, a homogenous embankment dam consisting of low plasticity clay (CL) or the clay core of a zoned embankment dam, must be compacted so that the clay material behaves more like a plastic material, i.e. deforms without a well developed failure plane. This study shows that, to ensure structural integrity of embankment dams in seismically active areas, the clay should not only be compacted wet of the OWC, but also on the wet side of the transition water content marking the boundary between brittle and plastic deformations.
