Abstract.

I will discuss the effective properties of a composite material whose micro-structure is constituted by a brittle material with periodically distributed soft inclusions. In particular, I will show that the presence of the soft inclusions gives rise, in the limit, to a cohesive behaviour and a toughening phenomenon.
