The maximum energy stored at elastic limit of a material is called

Explanation:

Proof resilience

• It is the energy absorbed per unit volume by a material up to the proof stress (yield point under certain conditions).

• It represents the material's ability to absorb energy without permanent deformation beyond the proof stress.

• Less commonly used term compared to modulus of resilience.

Additional InformationModulus of resilience

• It is the maximum energy per unit volume that a material can absorb without permanent deformation, i.e., up to the elastic limit or yield point.

• Calculated as the area under the stress-strain curve up to the elastic limit.

• Important in design for materials subjected to sudden or impact loads.

Resilience

• General term for the ability of a material to absorb energy when deformed elastically and release it upon unloading.

• It can be considered as the total energy absorbed before failure (elastic + plastic), but often loosely used.
