What are the Properties of materials ?

Properties of materials:-

 Physical properties
     1) colour
     2) Density

Mechanical properties

 1) Strength :- It is defined as the ability of a material that can restained the mechanical load.

2) Hardness:- It is defined as the resistance offered by Material against mechanical deformation.

3) Fracture toughness :- It is defined as the ability of a material that can absorbed energy upto the failure.

4) Ductility :- It is defined as the ability of a material that can undergoes plastic deformation before failure takes place.

5) Stiffness :- It is defined as the ability of a material to resist the mechanical deformation under stress .

6) Brittleness :- It is defined as the ability of a material that can resist the mechanical load without plastic deformation.

7) Creep:- It is defined as the time vs strain behaviour of a material under constant mechanical load.

8) Fatigue :- It is defined as the time vs strain behaviour of a material under oscillating mechanical load.

9) Resilience :- It is defined as the ability of a material that can absorb energy against shock and impact load without its shape changes.

10) Malleability :- It is defined as the ability of a material to drawn into thin sheets and wires.
