Elastic Modulus Calculator
Calculate Young's modulus using E = σ / ε. Enter stress in MPa and strain to get the elastic modulus in GPa.
How to Use the Elastic Modulus Calculator
- Enter the measured stress in MPa.
- Enter the corresponding strain value (e.g. 0.001).
- Click Calculate to get Young's modulus in GPa.
Casos de Uso
- •Processing tensile test results.
- •Determining the modulus of a new material.
- •Verifying material data against experimental results.
Fórmula
E = σ / ε, where E is Young's modulus (GPa), σ is stress (MPa), and ε is strain (dimensionless).
Preguntas Frecuentes
What is Young's modulus?
Young's modulus is the ratio of stress to strain in the elastic region. It characterises a material's stiffness under tension or compression.
What are typical Young's modulus values?
Steel: ~200 GPa, cast iron: ~170 GPa, aluminium: ~69 GPa, copper: ~120 GPa, titanium: ~116 GPa, glass: ~70 GPa.
How is elastic modulus measured experimentally?
From a tensile test, take the slope of the linear portion of the σ-ε diagram. The strain must be below the yield point.
