The objective of this work is to obtain the mapping of the granular flow during the irreversible deformation processes in spatially extended polycrystalline systems (SEPCS) in order to describe and analyse the phenomenology and mechanics of the granular flow. In general, it was established for commercial alloys that, the granular flow is linked with the hyperbolic motion due to dislocation dynamics and self accommodation of grains. Also, the recession velocity of grains in the stain field on the surface of SEPCS increased with the distance along the tension axis from the origin of the coordinate system of reference. This behaviour is very similar to the Hubble flow associated with the expansion process of the universe, where the recession velocity of the galaxies increased in a linear relationship with their distance. In this physical framework the main results are analysed in the context of the unified interpretation of the Hubble flow, plastic flow and super plastic flow [1-6].
