Q33. If a simple Maxwell model and a simple Voigt model for viscoelastic flow are loaded at time to, held for a certain time t, and then unloaded, what is different about their responses during the loading and unloading processes? And, what is different about the final state of the two mechanical models? Sketch a plot of strain vs. time for both cases to illustrate your descriptions. Q33.
