CStrain energy
-
DImpact energy
Answer
Correct Answer: Strain energy
Explanation
DefinitionsStrain energy: total elastic energy stored by a body under load, recoverable upon unloading (within elastic limit).Resilience: ability to absorb energy elastically; commonly expressed as strain energy per unit volume.Proof resilience: maximum strain energy stored up to the elastic limit.Impact energy: energy absorbed during impact testing (fracture toughness context).
Final AnswerStrain energy.
