Abstract

In this work we study the elastic-plastic transition of the spatially extended polycrystalline austenitic stainless steel 304 (SEPC-ASS-304) advanced materials during an irreversible deformation process. Such transition was characterized by means of the fractal dimension computed of a sequence of digital images of the mesostructure of the SEPC-ASS-304 surface, obtained during the elastic-plastic transition. Our results show a correlation between the fractal dimension and the evolution of the granular flow during the deformation of such advanced material.
