📏 True Strain Calculator
Calculate true strain, engineering strain, and strain relationships for material deformation
📐 True Strain Formulas
ε_true = ln(L/L₀)
ε_true = ln(1 + ε_eng)
ε_true = ln(A₀/A)
ε_true = ln(V₀/V)
ε_true = true strain, ε_eng = engineering strain, L = final length, L₀ = original length, A = final area, A₀ = original area, V = final volume, V₀ = original volume
💡 Tips
- True strain accounts for changing geometry during deformation
- True strain is always larger than engineering strain
- True strain is additive for multiple deformations
- Use true strain for large deformations
- Engineering strain is adequate for small deformations
- True strain is used in finite element analysis
