Engineering properties of different materials

1. Strength:

It is the property of material by which it can sustain the load.

2. Elasticity:

It is property of material by virtue of which it can regains its original size and shape after deformation on removing load causing deformation.

3. Plasticity:

It is property of material by virtue of which it can not regains its original size and shape after deformation on removing load causing deformation.

4. Ductility:

It is property of material by which it can under goes considerable deformation under tension before its failure.

5. Brittleness:

It is property of material by which it can not under goes considerable deformation under tension before its failure.

6. Malleability:

It is property of material by which it can under goes permanent deformation under compression with out its failure.

7. Toughness (impact strength):

It is property of material by virtue of which it can absorb suddenly applied load with out its failure.

8. Hardness:

It is property of material by virtue of which it can resist wear, abrasion and scratching.

9. Stiffness:

It is property of material by virtue of which it can resist elastic deformation.
OR
Mathematically it is load required to produce unit deformation.

10. Creep:

It is property of material by virtue of which it undergoes continuous deformation under steady load with time.
It is also called as 'Time yield' or ' Plastic flow'.
