A new ductility exhaustion model for high temperature low cycle fatigue life prediction of turbine disk alloys
Download2011
Zhu, Shun-Peng, Sun, Rui, Zuo, Ming J., Li, Haiqing, Huang, Hong-Zhong
Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

Keyghobadi, N., Roland, J., Fownes, S.
We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...

β-Glucan is a soluble fibre shown to help regulate blood sugar and lower cholesterol. Incorporation into food, particularly bread, may affect β-glucan’s physicochemical properties and health benefits. The journey of β-glucan through the mixing, fermenting, baking, and storage of bread was...

The minable oil sands extraction process can be understood on a scale of a single oil sand grain. When the oil sand ore is mixed with warm water, each sand granule is initially covered with bitumen film which ruptures under the composite effect of shear and interfacial forces, while water...

Craster, R. V., Flynn, M.R., Bhattacharya, S.
By adapting the Föppl-von Kàrmàn equation, which describes the deformation of a thin elastic membrane, we present an analysis of the buckling pattern of a thin, very viscous fluid layer subject to shear in an axisymmetric geometry. A linear stability analysis yields a differential eigenvalue...

Development of an Experimental Apparatus for Studying the Effects of Acoustic Excitation on Viscosity
DownloadFall 2012
An experimental apparatus was developed capable of measuring changes in fluid viscosity occurring due to acoustic stimulation. Controls allowed measurements at simulated oil sand reservoir pressures and temperatures with near real-time data visualization. Calibration was performed...

Unconventional oil reserves are taking an increasing importance globally due to the decrease of conventional sources of hydrocarbons. Oil sands industry plays an important role in the production of unconventional bitumen, through proven technologies such as surface mining and in situ extraction...

Effects of viscosity and fermentability of dietary fibre on nutrient digestibility and digesta characteristics in ileal-cannulated grower pigs
Download2011
Vasanthan, Thavaratnam, Zijlstra, Ruurd T., Metzler-Zebeli, Barbara U., Hooda, Seema
Relative contributions of two functional properties, viscosity and fermentability of dietary fibre, on apparent ileal digestibility (AID), apparent total tract digestibility (ATTD), digesta passage rate, N retention and SCFA concentration have not been established. Thus, eight ileal-cannulated...

Marleau, L. J., Sutherland B.R., Flynn, M.R.
Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they approach and then propagate up a rising slope. Consistent with the prediction of a WKB-like theory, the gravity current front decelerates in a nearly uniform manner along...
