The Formal Structure of Linear Viscoelasticity

Gross [7] has discussed the formal structure of the theory of linear viscoelasticity. A summary of his treatment will be presented here, as a suitable conclusion to our discussion. 

Group 1 Experiments that take place under a given stress, either fixed or alternating. These define the creep compliance or the complex compliance. 

Within each group, the viscoelastic functions exist in three levels  

To go up a level, one applies either a Laplace transform or a one-sided complex Fourier
