WebSep 2, 2024 · In pure bending (only bending moments applied, no transverse or longitudinal forces), the only stress is σ x as given by Equation 4.2.7. All other stresses are zero ( σ y = σ z = τ x y = τ x z = τ y z = 0 ). However, strains other than ϵ x are present, due to the Poisson effect. WebThe bending moment, M, along the length of the beam can be determined from the moment diagram.
