WebJun 2, 2024 · Brittle materials like ceramic, glass and graphite undergo linear elastic deformation with little to no plastic deformation before fracture. Not all materials exhibit linear elasticity. In fact, there is whole class of materials that will undergo huge elastic deformations at strains above 100% upon load application and fail with no plastic ... 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 …
