PROPERTIES OF ENGINEERING MATERIALS

Some important properties of Engineering materials are -

1. ELASTICITY - Elasticity may be defined as the property of a material to regain its original shape or dimension when the applied force is removed.

2. PLASTICITY - Plasticity may be defined as the property of a material due to which material is unable to regain its original shape even after the removal of applied force.

3. DUCTILITY - Ductility may be defined as the property of a material to be drawn into wires without breaking

4. BRITTLENESS - Brittleness may be defined as the property of a material to break without deformation when an external force is applied. It is an undesirable property. The lack of Ductility is known as Brittleness.

eg - Cast Iron , High Carbon Steel

5. MALLEABILITY - Malleability may be defined as the property of a material  to be drawn into thin sheets without breaking.

6. TOUGHNESS - Toughness may be defined as the property of a material to absorb energy under impact loading.

7. HARDNESS - Hardness may be defined as the property of a material to resist indentation.

8. STRENGTH - Strength may be defined as the property of material to withstand applied load without fracture.
