Young's modulus (E) measures resistance to axial deformation: E = stress / strain; defines material stiffness.
Formule
Calculate E = σ/ε
- E
- σ/ε — σ/ε
Guide étape par étape
- 1Input axial stress and resulting strain
- 2Calculate E = σ/ε
- 3Results show material stiffness, usually in GPa
Exemples résolus
Entrée
Steel: E ≈ 200 GPa
Résultat
Aluminum: E ≈ 70 GPa
Steel ~3× stiffer
Erreurs courantes à éviter
- ✕Confusing with strength (high E ≠ strong)
- ✕Not using consistent units
Questions fréquentes
Does Young's modulus depend on material processing?
Slightly; annealing can reduce E, cold-working can increase it, but primarily material-dependent.
