  • Angle of repose Wikipedia

    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 area and shapes of the particles, and the coefficient of friction of the material. Material with a low angle of repose forms flatter piles than material with a high angle of repose.

  • Angle of Internal Friction on the Geotechnical Information

    Angle of internal friction for a given soil is the angle on the graph (Mohr's Circle) of the shear stress and normal effective stresses at which shear failure occurs. Angle of Internal Friction, f, can be determined in the laboratory by the Direct Shear Test or the Triaxial Stress Test.

    The friction angle of the soil is an indior on how well the soil will support its own weight. Soils also possess a second property which allows the soil to stick together, cohesion. Clay soils have lower internal strengths but higher cohesion values. Soils with high percentages of sand and gravel have higher internal strengths
