Beam Stress & Deflection Calculator
Preliminary elastic bending analysis for common beam configurations. Calculate maximum bending stress and deflection for simply supported or cantilever beams under point or distributed loads.
Inputs
Beam & loading
Simply supported beam · center point load
Bending moment diagram
Calculate to plot the bending moment distribution.
Results
Enter the inputs and calculate.
Method & assumptions
- Linear elastic beam theory (Euler-Bernoulli), rectangular solid cross-section.
- Second moment of area I = b·h³/12. Section modulus S = I/(h/2).
- Maximum bending stress σ = Mmax/S.
- Standard closed-form deflection formulas for each supported/cantilever load case.
Engineering aid only. This does not assess shear stress, buckling, combined loading, non-rectangular sections, fatigue or detailed design-code requirements.
