Compactness and lower semicontinuity in $GSBD$

Abstract

In this paper, we prove a compactness and semicontinuity result in GSBDGSBD for sequences with bounded Griffith energy. This generalises classical results in (G)SBV(G)SBV by Ambrosio and SBDSBD by Bellettini-Coscia-Dal Maso. As a result, the static problem in Francfort-Marigo's variational approach to crack growth admits (weak) solutions. Moreover, we obtain a compactness property for minimisers of suitable Ambrosio-Tortorelli's type energies, for which we have recently shown the Γ\Gamma-convergence to Griffith energy.
