Barchiesi, MarcoLazzaroni, GiulianoZeppieri, Caterina Ida2015-01-262015-01-262015https://openscience.sissa.it/handle/1963/7492We 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 ε to obtain, in the limit as ε tends to zero, a homogeneous macroscopic energy-functional explicitly depending on the opening of the crack.enΓ-convergenceFree-discontinuity problemsfracture mechanicsmultiscale analysishomogenisationPreprint
