| PROPERTIES OF MATERIALS (NOTES) | |
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. EG. Casting molten metal 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 and tear and indentation. CONDUCTIVITY: The ability of a material to conduct electricity. |
