The analysis of phenomenological modeling of elastoviscoplasticity properties of bulk nanostructures is executed. The determining equations of interrelation of deformation and durability properties of initial and nanostructural bulk materials are constructed on the basis of endochronic concepts to the data of diagrams of their stretching, with the use of "vertical" and "horizontal" scales of generalized time depending on parameters of structure and manufacturing techniques. Examples of application of the approach to metals and fulleren-polymeric composites are considered.
