The viscoelastic fluids showed a trade-off between shear thinning and elasticity. Thtee fluids were Boger-like in that they exhibited nearly constant viscosity in simple shear but had significant elasticity. Two liquids obeyed the Carreau model but showed significant elasticity. AJl five liquids exhibited varying degrees of the Weissenberg effect.

Viscoelastic Materials - an overview | ScienceDirect… Viscoelastic behavior also depends on temperature because material stiffness changes with temperature. In selecting materials for clinical application, it is important to know what will be the corresponding viscoelastic response at an appropriate loading rate and temperature.
