Abstract

Bedding angle is a fundamental property of a particulate system that describes the resistance to rolling motion of a single grain. Mean trends of the bedding angle of sand have been described in the literature. This research expands upon the work to date by investigating the distribution of bedding angle for sands. Experimental measurements of bedding angle distributions are made for eight sands. Additionally, a theoretical description of the variability of bedding angle as a function of random grain size is developed and implemented numerically. The shape of the bedding angle distribution is found to be simulated well from the numerical simulations; the mean value of bedding angle is best predicted from particle roundness and empirical relationships. Together, these procedures provide a means of predicting the complete distribution of bedding angle for any given sand.
