Can I use this calculator for beams with non-standard shapes?

The tool currently supports only the listed standard cross-sections (square, rectangle, circle, I-beam, etc.). For custom shapes, you would need to calculate the section modulus manually or use a more specialized engineering software.

What units should I use for the bending moment and dimensions?

The calculator accepts standard length and force units; consistent units must be used throughout (e.g., Newtons and meters, or pounds and inches) to ensure the stress result is accurate.

Does the calculator account for beam deflection or only stress?

This specific calculator focuses on maximum bending stress. Deflection results are available in other Omni Calculator beam tools, but not within this particular stress-focused interface.

Is the bending stress result affected by the beam's length?

No, the bending stress calculation depends on the applied moment and the cross-section's section modulus, not the beam's overall length. Length influences the bending moment itself, which you would input separately.

About this tool

What Bending Stress Calculator does

This free online tool computes the maximum bending stress on a beam given its cross-section and the applied bending moment. It supports a wide range of common shapes—square, rectangle, rectangular tube, tee, channel, I-beam, angle, solid circle, and hollow circle or pipe—allowing users to model the beam’s geometry and instantly see the resulting stress. The output includes the maximum bending stress (σ max) and can be shared via a link. While a paid upgrade unlocks advanced features, the base calculator provides core stress analysis at no cost. Compared to other beam calculators, this version distinguishes itself through its extensive cross-section library and the site’s straightforward, label-driven interface that requires no account or software download. It also embeds explanatory text directly on the page, helping users understand the stress concepts without leaving the calculator.
