viscoelasticity

[¦vis·kȯ‚i‚las′tis·əd·ē]
(mechanics)
Property of a material which is viscous but which also exhibits certain elastic properties such as the ability to store energy of deformation, and in which the application of a stress gives rise to a strain that approaches its equilibrium value slowly.
