Research was initiated by Federal Aviation Agency and contract awarded to Douglas Aircraft and McDonnel Aircraft, who conducted study of fracture toughness characteristics of metals and crack propagation and crack arresting techniques for pressure cabin construction; paper presents results of tests on centrally notched fracture toughness specimens of steels, titaniums, and superalloys, and results of testing cracked specimens under uni- and bi-axial states of stress at various temperatures, and extent of material deterioration in stiffened panels; methods of analyses for crack propagation and residual crack strength are given.
