stress and strain is very important. When an external force is applied on a
body, it starts to deform. the external force applied on the body induces a
resisting force within the body, when this resisting force is taken on unit
area is called stress. There is a change in the dimension of the body due to
the induced stress. The ratio of this change in dimension with the original
dimension of the body is called strain.
Difference Between Stress and Strain in Tabular Form
Comparison Between Stress and Strain
The various comparison between stress and strain are as follows:
- Stress is the resisting force per unit area where as strain
is the deformation per unit area. - The stress is given by the ratio of resisting force to the cross
section area of the body. The strain is given by the ratio of change in
dimension to the original dimension. - The stress is denoted by the symbol ‘σ’ and strain by ‘e’.
- The unit of stress is N/m2 or N/mm2
whereas the strain does not have units. - The stress can exist without strain but the existence of
strain without stress in not possible.
