Fracture toughness (K_IC) is resistance to crack propagation: higher means harder to break even with flaws.
단계별 가이드
- 1Input material properties and defect size
- 2Calculate stress intensity factor
- 3Determine fracture criterion
풀어진 예시
입력
Steel K_IC ≈ 100 MPa√m (tough)
결과
vs. Ceramic K_IC ≈ 5 MPa√m (brittle)
피해야 할 일반적인 실수
- ✕Confusing toughness with strength
- ✕Not accounting for stress concentration
자주 묻는 질문
Why do ceramics have low toughness?
No crack blunting mechanism; brittle failure from small flaws.
