Chapter 4: Materials Vocabulary

Stiffness

Resistance to deformation under the action of an applied force e.g. in tension. Steel is a Tough material

1 of 6

Strength

Resistance to breaking under the action of an applied force. Steel is a very strong material

2 of 6

Toughness

Resistance to cracking. The material fails through permanent plastic deformation by absorbing energy. Leather is tough.

3 of 6

Brittleness (opposite of tough)

Prone to cracking. The material fails through crack propagation. Glass and ceramics are brittle.

4 of 6

Ductility

Ability to be drawn into wire. Copper and Lead are ductile.

5 of 6

Hardness

Resistance to indentation or scratching. Diamond was the hardest known material.
