Fracture toughness (K_IC) is resistance to crack propagation: higher means harder to break even with flaws.

  1. 1Input material properties and defect size
  2. 2Calculate stress intensity factor
  3. 3Determine fracture criterion

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Steel K_IC ≈ 100 MPa√m (tough)
ଫଳ
vs. Ceramic K_IC ≈ 5 MPa√m (brittle)

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Confusing toughness with strength
  • Not accounting for stress concentration

ବାରମ୍ବାର ଜିଜ୍ଞାସା

Why do ceramics have low toughness?

No crack blunting mechanism; brittle failure from small flaws.
