WebApr 13, 2024 · The internal friction angle \({\beta }_{in}\) is not included in Eq. because the Lee–Shaffer theory assumes that internal friction occurring between materials with the same lattices should have a constant angle of 45°. This assumption does not account for the effects of the material inner structures or transformation of the material state ... WebFigure 6.10 Frictional forces, such as f →, f →, always oppose motion or attempted motion between objects in contact. Friction arises in part because of the roughness of the surfaces in contact, as seen in the expanded view. For the object to move, it must rise to where the peaks of the top surface can skip along the bottom surface.
