Angle of repose - Wikipedia

11-3-2004· 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 morphology of the material affects the angle of repose; smooth, rounded ...

Angle of Repose - an overview | ScienceDirect Topics

Angle of repose is another important physical property used for characterization of the bulk of particulate foods such as seeds, grains, flours, grits, and fruits. When granular solids are piled on a flat surface, the sides of the pile are at a definite reproducible angle with the horizontal leveled surface (Fig. 3.8).This angle is called the angle of repose of the material.
