The Fracture Toughness of Beryllium



Data on the fracture toughness of beryllium obtained by the authors and that available in the literature are reviewed. The effects of test method, chemistry and microstructure, temperature and strain rate, and fracture modes are discussed. The available data suggest that the fracture toughness of both hot pressed and sheet beryllium is proportional to the product of the true fracture stress and true fracture strain. A rationale for this correlation is developed on the basis of the Griffith-Orowan fracture equation. The effects of temperature and strain rate on the fracture toughness of beryllium sheet follow an Arrhenius-type relation which is in accord with that for prism slip.
