Material Fatigue Calculator
Estimate fatigue life using the Basquin equation with Goodman mean-stress correction.
How to Use the Material Fatigue Calculator
- Enter the stress amplitude in MPa.
- Enter the endurance limit of the material.
- Enter ultimate tensile strength.
- Enter the stress ratio R.
使用例
- •Fatigue life prediction
- •Machine component design
- •Structural integrity assessment
計算式
N = (S_e / σ_a)^(1/b); Goodman: σ_a/S_e + σ_m/S_u = 1
