We prove that a class of free-discontinuity problems with nonisotropic bulk and surface energy densities is approximated, in the sense of Gamma-convergence, by suitable families of nonlocal integral functionals. Some connections with the Wulff set are also pointed out.

Abstract
We prove that a class of free-discontinuity problems with nonisotropic bulk and surface energy densities is approximated, in the sense of Gamma-convergence, by suitable families of nonlocal integral functionals. Some connections with the Wulff set are also pointed out.File in questo prodotto:
