Return to the original shape when the applied load is removed.
Elastic means reversible
Viscous Deformation
Plastic deformations in noncrystalline solids (as well as liquids) occurs by a viscous flow mechanism. Usually attributed to fluids. But solids may also behave like viscous materials under high temperature and pressure.
Viscous materials deform steadily under stress.
Deformations are time dependent
