A review on the angle of repose of granular materials

2018. 5. 1. Metcalf investigated the relationship between the internal friction angle and the angle of repose of crushed rocks on the basis of physical experiments. He concluded that the angle of repose, in general, is not equal to the angle of internal friction of the heaped material but is the angle of internal friction for the same material under its loosest condition.

Macro- and micro-mechanical characteristics of crushed

2015. 3. 1. Crushed rock aggregate is widely used as railway ballast and embankment filling in civil engineering. In permafrost regions, crushed rock subgrade has been used to cool the basement, which can be divided into crushed rock cushion subgrade, rubble slope subgrade, and U-type gravel subgrade laying crushed rock both on the slope and the bottom of the subgrade ( Mu et al., 2010 ), as shown in

Angle of repose Wikipedia

2021. 4. 2. 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
