contents In this paper we study the asymptotic behavior of a family of discrete functionals as the lattice size, $\varepsilon>0$, tends to zero. We consider pairwise interaction energies satisfying $p$-growth conditions, $p<d$, $d$ being the dimension of the reference configuration, defined on discrete functions subject to Dirichlet conditions on a $δ$-periodic array of small squares of side $r_δ\sim δ^{d/d-p}$. Our analysis is performed in the framework of $Γ$-convergence and we prove that, in the regime $\varepsilon=o(r_δ)$, the discrete energy and their continuum counterpart share the same $Γ$-limit and the effect of the constraints leads to a capacitary term in the limit energy as in the classical theory of periodically perforated domains for local integral functionals.
