Fracture toughness (K_IC) is resistance to crack propagation: higher means harder to break even with flaws.
ステップバイステップガイド
- 1Input material properties and defect size
- 2Calculate stress intensity factor
- 3Determine fracture criterion
解いた例
入力
Steel K_IC ≈ 100 MPa√m (tough)
結果
vs. Ceramic K_IC ≈ 5 MPa√m (brittle)
避けるべきよくある間違い
- ✕Confusing toughness with strength
- ✕Not accounting for stress concentration
よくある質問
Why do ceramics have low toughness?
No crack blunting mechanism; brittle failure from small flaws.
