WebBeam Bending Stress The strain equation above can be converted to stress by using Hooke's law, σ = Eε, giving, σ = -Ey/ρ (1) There is still the issue of not knowing the radius of curvature, ρ. If one thinks about it, the radius of curvature and the bending moment should be related. Beam Section Cut WebA number of simple examples are shown below. The formulas expressed are approximations developed for long, slender, homogeneous, prismatic beams with small … A beam deforms and stresses develop inside it when a transverse load is applied on it. In the quasi-static case, the amount of bending deflection and the stresses that develop are assumed not to change over time.
