Bearing Stress Calculator
Contact crushing stress between pin and hole, or plate and support.
Bearing allowables run HIGHER than tension (1.2โ1.5รf_y) because the material is confined โ but thin sheet still wallows holes egg-shaped long before anything breaks.
Formula
Bearing Stress Calculator is a free bearing stress for design engineers, metallurgists and QA inspectors โ 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 Bearing Stress Calculator
Contact crushing stress between pin and hole, or plate and support. The calculation implements ฯ_b = P/(dยทt) โ projected area (IS 800 / AISC bearing provisions). Bearing allowables run HIGHER than tension (1.2โ1.5รf_y) because the material is confined โ but thin sheet still wallows holes egg-shaped long before anything breaks.

Frequently asked questions
What formula does the Bearing Stress Calculator use?+
It computes ฯ_b = P/(dยทt) โ projected area, per IS 800 / AISC bearing provisions. 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?+
Bearing allowables run HIGHER than tension (1.2โ1.5รf_y) because the material is confined โ but thin sheet still wallows holes egg-shaped long before anything breaks.
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 Bearing Stress Calculator free to use?+
Yes โ 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.
