Modelling in non-linear viscoelasticity

We may see that the modeling of viscoelastic response on the effects of external loading of structures is rather complicated, provided by suitable selection of set of the parameters for determination the stress-function F [σ (t)]. A given case one-dimensional problem was solved. Different method for approximation of solution of the given problem is represented by the so-called geometrical principle of homothety of creep curves and isochrone curves. Presented process of problem solution from the mathematical point of view is not demanding and thus it is widely used in practice.
