In this paper, a multi-scale analysis is presented for nucleation and growth of a microcrack in front of a macrocrack. The loading conditions of the elementary cell are determined at the mesoscopic level in order to perform an analysis of the microcrack growth at a microscopic level. Both the influence of the inclusion shape in the cell and the state of stress on the mechanism of material failure near the crack tip are analyzed. The relations between the mechanical properties of the inclusion and the matrix are determined, causing different mechanisms of damage to be experimentally observed.
