Angle of Repose - DataGenetics

There is a critical angle (which we now know is the Angle of Repose), after which, the walls are no longer able to support the particles and they slide inwards. Wet sand has a higher coefficient of friction than dry sand, so it is …


Angle of Repose and Internal Friction | Friction | Materials

Abstract--The relation between angle of repose and angle of internal friction in a fragmented mass is discussed, and experiments with crushed rocks are reported. It is concluded that the angle of repose is not generally the angle of internal friction of the material in the pile, but of the same ...
