Abstract:
A homogenization result is given for a material having
brittle inclusions arranged in a periodic structure. According to the relation between the
softness parameter and the size of the microstructure, three different limit models are deduced via
Gamma-convergence. In particular, damage is obtained as limit of periodically distributed
microfractures.
