Axial Stress Calculator
P/A with utilisation against yield — the fastest of all checks.
Uniform P/A holds only away from holes, fillets and load points (Saint-Venant) — everywhere else, multiply by a stress-concentration factor first.
Formula
Axial Stress Calculator is a free axial stress for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Axial Stress Calculator
P/A with utilisation against yield — the fastest of all checks. The calculation implements σ = P/A (Strength of materials fundamentals). Uniform P/A holds only away from holes, fillets and load points (Saint-Venant) — everywhere else, multiply by a stress-concentration factor first.

Frequently asked questions
What formula does the Axial Stress Calculator use?+
It computes σ = P/A, per Strength of materials fundamentals. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Uniform P/A holds only away from holes, fillets and load points (Saint-Venant) — everywhere else, multiply by a stress-concentration factor first.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Axial Stress Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
