Mechanical vibration → Useful heat

Matrix context

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

   Mechanical vibration —drives→ Elastic deformationestablishedclaim record

   mechanical → mechanical · loss to thermal

   • cyclic deformation of an elastic member (a cantilever
   • a plate
   • a sheet) by base or inertial excitation; operation at a structural resonance amplifies the deformation but is not required

   solid

   refs [1] [2] [3]
2. 02
   Elastic deformation —produces→ Mechanical stress or strainestablishedclaim record

   mechanical → mechanical

   • the deformed member carries a cyclic stress or strain state that can drive a stress-driven conversion (flexoelectric
   • elastocaloric
   • piezoelectric)

   refs [4] [1]
3. 03
   Mechanical stress or strain —drives→ Elastocaloric effectreplicatedclaim record

   mechanical → thermal

   • stress large enough to drive the martensitic transformation of a shape-memory alloy
