Elastocaloric heat pump
An elastocaloric heat pump is a solid-state heating and cooling device that pumps heat by mechanically loading shape-memory alloys, needing no compressor or fluorinated refrigerant.
Elastohydrodynamic lubrication
Elastohydrodynamic lubrication (EHL) is a form of hydrodynamic lubrication where elastic deformation of the surfaces and a sharp rise in lubricant viscosity under pressure create the separating film.
Elastoplastic model
An elastoplastic model is a constitutive model of solid mechanics that describes deformation as a recoverable elastic part plus a permanent plastic part once a yield criterion is reached.
