WebThe soil is a particulate material. The shear failure in soils is by slippage of particles due to shear stresses. According to Mohr, the failure is caused by a critical combination of normal and shear stresses. The soil fails when the shear stress on the failure plane at failure is a unique function of the normal stress acting on that plane. WebSep 2, 2024 · Constitutive equation: The stresses are obtained directly from Hooke’s law as (4.2.4) σ x = E ϵ x = − y E v, x x This restricts the applicability of this derivation to linear elastic materials. Hence the axial normal stress, like the strain, increases linearly from zero at the neutral axis to a maximum at the outer surfaces of the beam. 4. good video how did you make the cat
