This paper presents a model for the investigation of sandstone degradation and sand production mechanisms coupled with fluid flow analysis using the Discrete Element Method (DEM). The model was used to investigate the effects of in-situ stresses and flow rate on sand production. We developed a...

Backcountry snowmobilers’ risk perceptions, avalanche related information seeking behaviours, preparedness and decision-making processes
DownloadFall 2013
Although there has been substantial research on the avoidance of risk, much less has been completed on voluntary risk. This study examined backcountry snowmobilers’ risk perceptions, avalanche related information seeking behaviours, and decision-making processes when dealing with avalanches and...

Laboratory testing of rocks is traditionally carried out to determine the peak strength using the ISRM Suggested Methods or other suitable standards. However, it is well known that in low-porosity crystalline rocks there are at least three distinct stages of compressive loading that can be...

Landslides include various forms of geological mass movements such as falls, slides and flows under the force of gravity. Predictions of landslide kinematics and dynamics require knowledge of flow behaviour and mathematical modeling. Research into the flow behaviour of granular materials has...

The Discrete Element Method (DEM) has been developed and used in modelling dry granular materials with or without cohesive bonding between particles. The incorporation of fluid flow in the DEM analysis is difficult since the DEM is a discrete approach to mechanistic analysis while fluid is a...
