Question

The Voight Model simulates the behavior of a viscoelastic polymer by placing a hookian and a viscous element in parallel.

a)    Write an equation for the stress strain behavior of the Voight model

b)    What are the conditions of stress and strain that define the creep and stress relaxation of the polymers?

c)     In a creep experiment, how would you expect the stress of the polymer to change as a function of time if:

h >> G

G>>h
