Calculation
E = σ / ε
E is the slope of the stress-strain curve; high values mean high stiffness.
E = σ/ε
Young's modulus from stress and strain
E is the slope of the stress-strain curve; high values mean high stiffness.

Result
Select a target and calculate.
Understand the inputs
- Young's modulus E — Material stiffness in the linear elastic range.
- Normal stress σ — Stress at the load point.
- Strain ε — Relative length change as a fraction.
Example
200 MPa / 0.001 = 200 GPa.
Assumptions and limits
Linear-elastic, isotropic material under uniaxial load.
