Definition of strain energy in English:

strain energy

noun

Mechanics
  • [mass noun] Energy stored in an elastic body under loading:

    ‘ligaments and tendons are elastic structures that can store strain energy, like a spring’
    ‘determinations of the form of the strain energy function’
    • ‘One has to realise that, in order for an earthquake to occur you have to accumulate strain energy.’
    • ‘These are elastic structures that can store strain energy, like a spring.’
    • ‘As a matter of fact, the zones here form as thin platelets to minimize strain energy.’
    • ‘That is, if the change in elastic strain energy due to crack extension is larger than the energy required to create new crack surfaces, crack propagation will occur.’
    • ‘Renewable stresses are those that persist because of continued re-application of the causative forces despite continual dissipation of the resulting strain energy.’
