Calcolatrice Modulo di Young — Formula
## Young's Modulus (Elastic Modulus)
Young's modulus quantifies material stiffness in the linear elastic region.
### Formula
**E = sigma / epsilon**
where sigma is the applied stress and epsilon is the resulting strain. E is measured from the initial linear portion of a tensile test stress-strain curve. Typical values: steel 200 GPa, aluminium 70 GPa, concrete 25-35 GPa, timber 8-14 GPa.

Esempio Risolto
A tensile test specimen shows 200 MPa stress at 0.001 strain.
- E = 200 / 0.001 = 200,000 MPa
- E = 200,000 / 1000 = 200 GPa
- This matches structural steel, confirming the specimen is steel.
