| Summary: | <p>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.</p> |
