WebMar 5, 2024 · 2.4.5. The Angle of Internal Friction. 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, φ, … WebJan 26, 2024 · It is an interface (soil-interface material) friction angle, rather than an internal (soil-soil) friction angle. You get it in the lab from interface friction tests, e.g. shearbox or ring shear. There are charts for estimating various friction angles of dissimilar materials (NAVFAC, AASHTO) as it is not practical to actually test for these ... blind by rachel dewoskin pdf
