viscoelasticityn.

Etymology: < visco- (in viscous adj.), visco- (in viscosity n.) + elasticity n.Previous versions of the OED give the stress as: ˌviscoelaˈsticity.

The property of a substance of exhibiting both elastic and viscous behaviour, the application of a constant stress causing an immediate deformation that disappears if the stress is quickly removed but increases for a time and becomes permanent if the stress is maintained.
