Questions and Answers

Which statement best describes the stress-strain behavior of metals?

  • Metals tend to exhibit brittle behavior with low strain values due to their strong directional bonds.
  • Metals tend to exhibit high strain values but lower stiffness and strength compared to ceramics and polymers.
  • Metals tend to exhibit lower Von Mises stress values compared to ceramics and polymers.
  • Metals tend to exhibit ductile behavior with higher strain values due to their metallic bonding. (correct)
