When bulk granular materials are poured onto a horizontal surface, a conicalpile will form. The internal angle between the surface of the pile and the horizontal surface is known as the angle of repose and is related to the density, surface areaand shapes of the particles, and the coefficient of frictionof the material. See more 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 on which the material can be piled without slumping. At this angle, the material … See more If the coefficient of static friction μs is known of a material, then a good approximation of the angle of repose can be made with the following function. This function is somewhat accurate for piles where individual objects in the pile are minuscule and piled … See more The angle of repose plays a part in several topics of technology and science, including: • Aeolian processes • Barchan See more The angle of repose is sometimes used in the design of equipment for the processing of particulate solids.
