Crack growth initiation and subsequent resistance in a hexagonal honeycomb made out of ductile base material is investigated in a numerical study. The elasto‐plastic base material is characterized by its yield strain, failure strain and the ratio of ultimate strength to yield strength, assuming a bilinear stress‐strain relationship. Of the base materials' fracture properties, only the specific fracture energy is prescribed. K‐Resistance curves are calculated under the assumption of small scale yielding.
