Daily Concept Booster Civil Engineering: DUCTILE AND BRITTLE MATERIAL

DUCTILE AND BRITTLE MATERIAL

Ductile material

If strain, post elastic strain is greater than 5%. It is called ductile material.

• Undergo large permanent strains before failure
• Large reduction in the area before fracture
• Example- Lead, mild steel, copper

Brittle material

If strain, post elastic strain is less than 5%. It is called brittle material.

• Fail with only little elongation after the proportional limit is exceeded.
• Very less reduction in the area before fracture
• Example- Bronze, Glass
• ‘Mild steel is more elastic than (Rubber).
