Shear Modulus Calculator
G from E and ν — the isotropic elastic-constant relations in one card.
Only TWO independent constants describe any isotropic material — given any two of (E, G, K, ν) the rest follow. Steel: G ≈ 77, K ≈ 167 GPa.
Formula
Shear Modulus Calculator is a free shear modulus 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 Shear Modulus Calculator
G from E and ν — the isotropic elastic-constant relations in one card. The calculation implements G = E/2(1+ν); K = E/3(1−2ν) (Theory of elasticity — isotropic relations). Only TWO independent constants describe any isotropic material — given any two of (E, G, K, ν) the rest follow. Steel: G ≈ 77, K ≈ 167 GPa.

Frequently asked questions
What formula does the Shear Modulus Calculator use?+
It computes G = E/2(1+ν); K = E/3(1−2ν), per Theory of elasticity — isotropic 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?+
Only TWO independent constants describe any isotropic material — given any two of (E, G, K, ν) the rest follow. Steel: G ≈ 77, K ≈ 167 GPa.
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 Shear Modulus 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.
