Abstract:

We provide a homogenisation result for the energy-functional associated with a purely brittle composite whose microstructure is characterised by soft periodic inclusions embedded in a stiffer matrix. We show that the two constituents as above can be suitably arranged on a microscopic scale $\varepsilon$ to obtain, in the limit as $\varepsilon$ tends to zero, a homogeneous macroscopic energy-functional explicitly depending on the opening of the crack.
