Stress & Strain

Compute stress (MPa), strain, and Young's modulus from force, area, and elongation.

Inputs

Force F

Cross-section Area A

mm²

Original Length L₀

Deformed Length L

Results

Stress σ = F/A—

Strain ε = ΔL/L₀—

Young's Modulus E = σ/ε—

σ = F/A (MPa) · ε = ΔL/L₀ · E = σ/ε

Stress and strain can be computed independently.
E requires both F/A and ΔL to be provided.
