This FLOW-3D simulation illustrates viscoelasticity through the classic oscillatory shear experiment. A rectangular fluid element sits between two plates. The top plate moves with a sinusoidal velocity, and the horizontal force at the bottom plate is measured throughout the cycle.
For a Newtonian fluid, the maximum force occurs when the top plate's velocity, and therefore the shear rate, is at its peak. For a purely elastic material, such as a solid, the maximum force instead occurs at the point of greatest displacement, when the top plate is most fully pivoted. A viscoelastic fluid's response falls between these two limits, reflecting the combined contribution of viscosity and elasticity to its overall behavior.
