The Griffith shape functional was introduced as the distributed shape derivative of the elastic energy evaluated in a domain with a crack, with respect to the crack length. The dependence of this functional on domain perturbation far from rupture was investigated. As a result, the directional shape and topological derivatives of the nonsmooth Griffith shape functional are obtained with respect to boundary variations of an inclusion."]
