Young's Modulus (Elastic Modulus) Calculator
Young's Modulus (Elastic Modulus) Calculator
Find a material's stiffness E = σ / ε from stress & strain, from raw tensile-test measurements, from multi-point stress-strain data, or estimate it from Shore hardness for rubbers and elastomers.

Reference: typical Young's modulus by material

Values are typical/representative ranges for general reference and comparison only — always confirm with mill certs, material spec sheets, or lab testing for design use.
What is a good Young's modulus value?
There's no single "good" value — it depends entirely on the application. Stiff structural metals like steel (~200 GPa) suit load-bearing frames; low-modulus elastomers (well under 1 GPa) suit seals and vibration isolation. Compare your result against the reference table above for context, not a pass/fail judgment.
Is Shore hardness the same as Young's modulus?
No. Shore hardness measures indentation resistance on a durometer scale, while Young's modulus measures tensile/compressive stiffness from a stress-strain slope. The two correlate for elastomers, which is why an empirical conversion exists, but they are physically different properties and the conversion is only approximate.
Why does my calculated E look too low?
The most common cause is including data points beyond the proportional limit, where the material has begun to yield. Only use points from the initial straight-line portion of the stress-strain curve — see the diagram above.
Can I use this for concrete or timber?
Concrete and timber are typically non-linear from very low stress, so "Young's modulus" is usually reported as a secant or tangent modulus at a specified stress level rather than a single constant slope. This tool computes a slope between your entered points, so choose points near the stress level relevant to your design check.
