Paano Kalkulahin si Fracture Toughness
Ano ang Fracture Toughness?
Fracture toughness (K_IC) is resistance to crack propagation: higher means harder to break even with flaws.
Step-by-Step na Gabay
- 1Input material properties and defect size
- 2Calculate stress intensity factor
- 3Determine fracture criterion
Mga Nalutas na Halimbawa
Input
Steel K_IC ≈ 100 MPa√m (tough)
Resulta
vs. Ceramic K_IC ≈ 5 MPa√m (brittle)
Mga Karaniwang Mali na Dapat Iwasan
- ✕Confusing toughness with strength
- ✕Not accounting for stress concentration
Mga madalas itanong
Why do ceramics have low toughness?
No crack blunting mechanism; brittle failure from small flaws.
