Fatigue Life ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Fatigue Life ಎಂದರೇನು?
Fatigue life estimation predicts component life under cyclic loading. Failure occurs at stress levels well below static strength.
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Use S-N curves or Miner's rule for fatigue analysis
- 2Calculate stress range and mean stress effects
- 3Account for surface finish, size, and stress concentration
Worked Examples
ಇನ್ಪುಟ್
Stress range 200 MPa, material steel, 10⁶ cycle life, actual 5×10⁸ cycles required
ಫಲಿತಾಂಶ
Life exceeded; fatigue safe
Approximate S-N curve lookup
Common Mistakes to Avoid
- ✕Using static stress limits for cyclic loading
- ✕Neglecting size effect on fatigue strength
Frequently Asked Questions
What is endurance limit?
Maximum stress below which infinite life is achieved (for steel ~0.5 × ultimate strength).
How do stress concentrations affect fatigue?
Stress concentrations reduce fatigue strength significantly; notches and holes are critical.
