Engineering Materials

PROPERTIES OF MATERIALS

• Strength. The ability of a material to stand up to forces being applied without it bending, breaking, shattering or deforming in any way.

• Elasticity. The ability of a material to absorb force and flex in different directions, returning to its original position.

• Plasticity. The ability of a material to be change in shape permanently.

• Ductility. The ability of a material to change shape (deform) usually by stretching along its length.

• Tensile strength. The ability of a material to stretch without breaking or snapping.

• Malleability. The ability of a material to be reshaped in all directions without cracking.

• Toughness. A characteristic of a material that does not break or shatter when receiving a blow or under a sudden shock.

• Hardness. The ability of a material to resist scratching, wear tear and identation.

• Conductivity. The ability of a material to conduct electricity.

The reason of this blog

This blog is an English homework. Students have to publish all we learn at english classes and practice sessions. This is an original learning way established in order to improve the student-teacher relationship far away of the class room.
