The materials which fracture even at small strains are termed as brittle, while those materials which exhibit an appreciable deformation before failure are termed as__________________?
Correct answer: C. Ductile
- A. Rigid
- B. Tough
- C. Ductile
- D. Plastic
Explanation
Ductile materials undergo appreciable plastic deformation before fracture, whereas brittle materials fail at small strains. Toughness refers to energy absorbed before fracture, so it is not the precise term asked for here.
