WebMohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope. Generally the theory applies to materials for which the compressive …
WebFeb 10, 2024 · soil friction strength. Occlusal friction refers to the friction caused by lifting, rotating and pulling out of the particles of the shear plane caused by the staggered arrangement of soil particles [37]. The angle of internal friction is an important factor influencing friction strength.
