Elastic Constants Converter (E, G → ν, K)
Measured E and G give you Poisson's ratio and bulk modulus instantly.
A consistency check too: if your measured E and G imply ν outside 0–0.5, one of the tests is wrong. It happens more often than labs admit.
Formula
Elastic Constants Converter (E, G → ν, K) is a free elastic constants 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 Elastic Constants Converter (E, G → ν, K)
Measured E and G give you Poisson's ratio and bulk modulus instantly. The calculation implements ν = E/2G − 1; K = E/3(1−2ν) (Isotropic elasticity relations). A consistency check too: if your measured E and G imply ν outside 0–0.5, one of the tests is wrong. It happens more often than labs admit.

Frequently asked questions
What formula does the Elastic Constants Converter (E, G → ν, K) use?+
It computes ν = E/2G − 1; K = E/3(1−2ν), per Isotropic elasticity relations. 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?+
A consistency check too: if your measured E and G imply ν outside 0–0.5, one of the tests is wrong. It happens more often than labs admit.
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 Elastic Constants Converter (E, G → ν, K) 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.
