🎯 Stress Concentration Factor Calculator
Calculate stress concentration factors for geometric discontinuities and notches
📐 Stress Concentration Factor Formulas
K_t = σ_max / σ_nom
K_t = 1 + 2√(a/ρ) (Elliptical Hole)
K_t = 3 (Circular Hole)
K_t = 1 + 2√(D/d) (Shoulder Fillet)
K_t = stress concentration factor, σ_max = maximum stress, σ_nom = nominal stress, a = semi-major axis, ρ = radius of curvature, D = larger diameter, d = smaller diameter
💡 Tips
- K_t > 1 indicates stress concentration
- Higher K_t means higher stress at discontinuity
- Sharp corners have higher stress concentration
- Fillets and rounded corners reduce K_t
- Consider fatigue effects for cyclic loading
- Use stress concentration charts for complex geometries
