The elastic of plastic deformation to fracture a material is its_______________?
Correct answer: D. Toughness
- A. Proportional limit
- B. Brittleness
- C. Young's modulus
- D. Toughness
Explanation
Toughness is the energy a material absorbs through elastic and plastic deformation before fracturing, represented by the total area under its stress-strain curve. Brittleness describes fracture with little plastic deformation, not energy absorption.
