Question

For elastomers, stress and strain variation is _________ within elastic limit.

Answer 1

The stress and strain graph for an elastomer is given above.

1. We can see that when low stress is applied a high strain is shown.
2. High strain results in high deformation.
3. When the stress is lifted, the elastomer returns back to its original shape.
4. If the strain applied crosses a breaking point, the object breaks.

Hence, for elastomers, stress and strain variation is not linear within the elastic limit.
