Strain : It is defines as ratio of change in dimension to original dimension.

Mathematically,

                           

There are three type of strain

1) Longitudinal strain : The ratio of change in length to original length is called as longitudinal strain.

2) Volume Strain : The ratio of change in volume  to original volume is called as volume strain.

3) Shearing  strain : The ratio of change in shape of a body  to original shape is called as shearing strain.
