On regularity for griffith almost-minimizers in the plane

M Friedrich, C Labourie, K Stinson - arxiv preprint arxiv:2310.07670, 2023 - arxiv.org
We present regularity results for the crack set of a minimizer for the Griffith fracture energy,
arising in the variational modeling of brittle materials. In the planar setting, we prove an …
