Stress Strain

Axial stress, strain, Young’s modulus and safety factor.

Formulas

• Stress σ = F/A.
• Strain ε = ΔL / L₀.
• Apparent E_obs = σ / ε; predicted ΔL = σ L / E.
• Safety factor SF = σ_y / σ.
• Strain energy density U = ½ σ ε.

Material presets cover common metals, concrete, wood and PLA.
