The fracture toughness of eggshell [PDF]

open access: yesActa Biomaterialia, 2016
The shells of avian eggs are very brittle, but how brittle? Fracture toughness, Kc is a standard measure used widely to characterise engineering materials. We devised a novel way to measure Kc and applied it to commercial hens' eggs, obtaining a value of 0.3MPa√m. This value is much lower than previous published values, which we argue are incorrect and
