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 possible to dig steeper sided holes in the wet.

angle of repose concept is of interest to coastal engineers for several reasons, including the stability of rubble- mound breakwaters and the modeling of sediment transport. (2) The angle of repose is a function of grain shape; it increases with increasing grain irregularity.

Abrasive Blasting Guide Abrasive blasting will produce an effect that may combine both a cleaning and finishing action. The finishing effect may vary by controlling such factors as hardness of the abrasive, abrasive particle size, velocity of abrasive stream, angle of abrasive gun, distance from the work, method of application and work flow.

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 ...

The cyclic triaxial system is used to investigate the effects of confining pressure, initial shear stress, cyclic stress ratio, and vibration frequency on the dynamic strength characteristics of saturated sand in the Wenchuan area. Results show that when the vibration frequency is constant, the dynamic strength of sand increases with the increase of the consolidation ratio.

The reason I chose to stay with sand (silica), is that glass beads are spherical and therefore have a lower angle of repose than does silica, which has a more irregular shape. This allows for steeper dune walls and greater detail.

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.
