Stretching Materials Keywords (copy)

Strong materials

Materials that have a high breaking stress, such as steel.

Weak materials

Materials that have a low breaking stress, such as expanded polystyrene.

Stiff materials

Materials with a high Young's Modulus, for example, steel.

Flexible materials

Materials with a low Young's Modulus, for example, natural rubber.

Tough materials

Materials that can absorb a lot of energy without breaking, such as mild steel, copper, and rubber tires.

Brittle materials

Materials that show little or no plastic deformation before breaking, such as glass and ceramics.

Elastic materials

Materials that regain their original size and shape when the deforming force is removed, such as steel in the Hooke's Law region.

Plastic materials

Materials that extend irreversibly when subjected to stress beyond the yield point, such as copper and modeling clay.

Hard materials

Materials that are difficult to scratch or indent, such as diamond.

Soft materials

Materials that are easy to scratch or indent, such as balsa wood and plasticine.

Ductile materials

Materials that can undergo large plastic deformation under tension, such as copper.

Malleable materials

Materials that can undergo large plastic deformation under compression, such as gold and bronze.
