angle of repose Angle of repose is ‘the constant three-dimensional angle assumed by a cone-like pile of material’ formed as powder flows onto a surface. 2,3 It is a function of the strength of interparticle forces, flatter cones being formed when these are weak. The more acute the angle of repose, the better the flowability of the

Angle of repose - Wikipedia

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.

the following conclusions can be made: (a) the angle of repose of the granular systems was influenced by the degree of roughness of the base on which the grains came to rest. The rougher the base was, the higher was the angle of repose; (b) the mode of failure of the conical pile of grains was different depending if the base was rough or smooth.
