Explain what is meant by a viscoelastic material, and relate its response to applied stresses by comparing the material with an elastic solid and a viscous fluid
What will be an ideal response?
Viscoelastic materials have some properties that are similar to elastic solids and some properties that are similar to viscous fluids. When a stress is applied to a viscoelastic material that is a solid, the solid will deform much like an elastic solid but will not immediately recover its original shape when the stress is removed. The viscoelastic material has used up some of the applied stress through internal heating, hence, not all of the energy is available to assist in the shape recovery.
