PROPERTIES OF MATERIALS
1. STRENGTH : Ability to withstand mechanical load.
2. HARDNESS: Ability to resist scratching, abrasion, cutting or penetrations.
3. DUCTILITY: Ability to deform like wires under tensile strength.
4. TOUGHNESS: Ability to absorb energy upto fracture.
5. ELASTICITY: Ability to return to its original position after deformation.
6. DENSITY: Ratio of mass of the material to its volume in homogeneous state.
7. MALIABILITY: Ability to form thin sheet without failure.
8. PLASTICITY: Ability to deform permanently without rupture.
9. BRITTLENESS: Ability to suddenly break into small pieces without deformation.
10. STIFFNESS: Ability to resist mechanical deformation.
11. CORROSION: Ability to resist environmental attack and decay.
12. CONDUCTIVITY: Ability to conduct electricity and heat.
13. DIELECTRIC: Ability to withstand at high voltage.
14. DIAMAGNETISM: Ability to repelled from the magnet.
Stress = Resistive Force/Area
Unit=N/mm2 or Pascal
1N/mm2 = 10^6 N/m2 = 1MPa
Strain = Change in dimension / Original Dimension
Unit=No unit
