כיצד לחשב את Fracture Toughness
learn.whatIsHeading
Fracture toughness (K_IC) is resistance to crack propagation: higher means harder to break even with flaws.

- 2Calculate stress intensity factor
- 3Determine fracture criterion
Worked Examples
קלט
Steel K_IC ≈ 100 MPa√m (tough)
תוצאה
vs. Ceramic K_IC ≈ 5 MPa√m (brittle)
Common Mistakes to Avoid
- ✕Confusing toughness with strength
- ✕Not accounting for stress concentration
Frequently Asked Questions
Why do ceramics have low toughness?
No crack blunting mechanism; brittle failure from small flaws.
