Abstract: The drift phenomenon of nonlinear elastic strain arising due to creep in conditions of linear stress on the basis of structural model of Maxvilles generalized two-tier model type is studied. On the basis of modeling material it is demonstrated that is the whole spectrum of diagrams of elastic strain is located between two stationary conditions: the diagram at $t=0$ and the diagram corresponding to the stage of established creep, thus instantly-elastic deformation shows simultaneously the properties of mechanical memory and viscoelasticity. The modeling calculations illustrating the effect investigated is executed.

Keywords: micronon-uniform materials, creep, Maxville's generic model, mechanical memory effect, elastic strain drift.
