Stress–Strain Calculator

How the Calculator Works

The calculator uses the fundamental mechanical formulas:

Stress  (σ) = Force / Area  
Strain (ε) = ΔLength / Original Length  
Young’s Modulus (E) = σ / ε
  

Stress is measured in Pascals (Pa), strain is dimensionless, and Young’s modulus is in Pascals.

Example

Force: 600 N  
Area: 0.003 m²  
Original Length: 1.5 m  
ΔLength: 0.002 m  

Possible Output:
Stress = 200000 Pa  
Strain = 0.00133  
Young’s Modulus = 150000000 Pa
