Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...

Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Nutrient distribution in sandy soils along a forest productivity gradient in the Athabasca Oil Sands Region, Alberta, Canada
DownloadFall 2016
Brunisolic soils developed on coarse textured (sandy loam to sand) deposits comprise a significant portion of the land currently being disturbed by surface mining in the Athabasca Oil Sands Region of Alberta, Canada. The goals of this study were to determine (i) how the physical properties of...

Lord, E. R. F., Hofmann, B. A., Fourie, A. B., Mikular, J., Robertson, P. K.
An opportunity to re–examine the liquefaction potential of hydraulically placed tailings sand has been provided by the Canadian Liquefaction Experiment (CANLEX). As part of this experiment, undisturbed samples of tailings sand were recovered after freezing the tailings in situ. Examination of...

Abstract: The Berkeley trigger criterion for evaluating the potential for earthquake-induced phenomena in sandy soils is reviewed in this paper. The historical database comprising the criterion is reconsidered using a consistent ''weakest-link-in-the-chain'' approach. Revised plots of average...

Abstract: Liquefaction failures of loose sand deposits can be a major concern for the stability of coastal structures. an investigation to evaluate the possible contributions of different triggering mechanisms in a major liquefaction failure that occurred in 1985 at the mouth of the Main Channel...

Finn, W. D. L., Robertson, P. K., Woeller, D.
Abstract: Impressive progress has been made in the last 25 years in recognizing liquefaction hazards, understanding liquefaction phenomena, and analyzing and evaluating the potential for liquefaction at a site. Recent findings related to the application of the seismic cone penetration test (SCPT)...

Abstract: Shear wave velocity (V-s) measurements were carried out in a triaxial testing program on three different cohesionless soils. The V-s was measured using bender elements during consolidation and at ultimate steady state. After consolidation the soil samples were loaded in shear under...

Robertson, P. K., Cunning, J. C., Sego, D. C., Sasitharian, S.
Abstract: The initial state of a sand, defined by the void ratio and effective mean normal stress, can be used to predict its large-strain response. Laboratory studies have shown that the shear-wave velocity of a sand is controlled primarily by the effective confining stresses and void ratio....
