ˌviscoelaˈsticity
[f. viscous a., viscosity + elasticity.]
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.
1944Q. Jrnl. Appl. Math. II. 119 The solution of the first and second boundary value problems of visco⁓elasticity is reduced to the solution of equivalent boundary value problems of elasticity, and the determination of the response of the visco-elastic material under consideration to a simple shearing stress or a simple shearing strain. 1963Times 27 Mar. 1/6 Viscosity and visco⁓elasticity of glasses. 1972Science 2 June 1041/3 The viscoelasticity of the solutions would decrease upon continued stirring. 1976Nature 12 Aug. 573/1 The explanation for the observed increase in cavitation erosion rate in polymer solution may still have its origin in polymer viscoelasticity.
So viscoeˈlastic a., exhibiting or pertaining to viscoelasticity.
