The Coefficient of Earth Pressure at Rest and Deformation and Densification of Granular Soils Subjected to Static and Dynamic Loading
… mainly the series of oedometer test with lateral stress measurement, were conducted on Ottawa, Lake Michigan Beach, Niigata, and Toyoura sand. Reconstituted dry sand specimens were subjected to 7 different loading histories, and the maximum effective vertical stress was 341 kPa. Different …

ANALYSIS OF THE EFFECTS OF HEAVILY LOADED MAT FOUNDATION ON ADJACENT DRILLED SHAFT FOUNDATION
… interaction between the foundations. However, lateral stress and drag forces on the shafts resulting from the heavy load on the mat foundation are the two major factors that would affect the design and performance of shafts. Since there is not much literature and guidance available to analyze …

Influence Of Cholesterol And Bilayer Asymmetry On Membrane Protein Distribution In Polymer-Tethered Raft-Mimicking Lipid Membranes
… may also impact membrane elastic properties and lateral stress within the bilayer. Previously it has been shown that phospholipid monolayers with elevated concentration of lipopolymers are able to respond to increasing lateral stress by inducing membrane buckling, a stress relaxation phenomena. …

A comparison of the behavior of intact and Resedimented Boston Blue Clay (BBC)
… conductivity, coefficient of consolidation, lateral stress ratio, preconsolidation pressure and peak friction angle of RBBC were within ranges for intact BBC. Ranges for secant friction angle, swell ratio and undrained strength for intact BBC overlapped and were lower than ranges reported for …

Swelling behaviour of unsaturated fine grained soils
… of various laboratory tests such as a 100 mm stress path triaxial cell and a computer controlled oedometer. Centrifuge modelling was used as a link between the laboratory tests performed and an existing prototype experimental wall. Three types of soils with different plasticity have been …

An experimental investigation into the stress-dependent mechanical behavior of cohesive soil with application to wellbore instability
… on specimens that were K0-consolidated to stress levels ranging from 0.15 to 10.0 MPa in both compression and extension shear modes. Compression tests were also performed on overconsolidated specimens. Model borehole tests make use of two new automated, high pressure Thick-Walled Cylinder …

Determining parameters for stiff clays and residual soils using the self-boring pressuremeter
… clay indicate that the clay exhibits high lateral stresses. They also indicate the existence of an anisotropic state of lateral stress which can be explained from the regional topography. The soil parameters interpreted from the SBPM test results in the Miocene clay compare well with the …

Diagnosing Bone Fracture to Assess Early Hominin Behaviour, Meat-Eating, and Socioecology at FLK-Zinjanthropus, Olduvai Gorge, Tanzania
… cones, incipient flakes, radiating cracks, and lateral stress features are characteristic of impact fracture, and e) Oldowan hominins at FLK-Zinj were responsible for breakage of 54% of the limb assemblage (a 37% – 40% increase over estimates based on percussion marks). The socioecological …

Performance of a propped retaining wall at the CTRL, Ashford
… prop loads, pore water pressures and<br/>lateral earth pressures were logged automatically at intervals of up to 5 minutes<br/>throughout construction (and for 4 years afterwards) and wall deflections were measured<br/>during construction, making this the most comprehensive instrumentation …

III-nitride nanowire light-emitting diodes: design and characterization
… dislocation densities, due to highly effective lateral stress relaxation. Nanowire light-emitting diodes (LEDs) with emission in the ultraviolet to visible wavelength range have recently been studied for applications in solid-state lighting, flat-panel displays, and solar-blind detectors. In …

Centrifuge modelling of the behaviour of geosynthetic-reinforced soils above voids
… a void in a controlled environment at realistic stress levels. A plane-strain model allowed visual observations of the deformation mechanisms using Particle Image Velocimetry. Granular soils and model clay liners were tested, as would be relevant to embankments and landfills respectively. These …

Factors affecting the initial stiffness and stiffness degradation of cohesive soils
This research investigated the pre-failure stress-strain behavior of cohesive soils through an ex.tensive testing program conducted on Resedimented Boston Blue Clay (RBBC). The uniformity and reproducibility in the behavior of this soil permitted a detailed study of the role of the following …
