The elastic strain energy is equal to the area under the stress-strain curve up (from origin to the elastic limit).

The elastic strain energy is equal to the area under the stress-strain curve up (from origin to the elastic limit). Correct Answer False

Elastic strain energy is equal to the area under the load vs elongation curve because the power is equal to force x distance. The area under the stress-strain curve up to the elastic limit is called resilience.
