In the presence of several pre-cracks, a brittle material always propagates only the weakest crack, leading to catastrophic failure. We show that all these features of brittle fracture are modified when the material susceptible to cracking is bonded to a hydrogel, a common situation in biological tissues. In the presence of the hydrogel, the brittle material can fracture in compression and can hydraulically resist cracking in tension. Furthermore, the poroelastic coupling regularizes crack tip dynamics and enhances material toughness by promoting multiple-cracking.
