Abstract: The fracture toughness of A533 steel at room temperature, 0 deg and −70 deg F, was evaluated with 1 and 2-in-thick contoured double cantilever beam (DCB) specimens. To establish the effect ...

Abstract: The Charpy “V” notch transition temperature of quenched and tempered armor steel was lowered by warm stretching at a temperature just below the initial tempering temperature. The transition ...

Abstract: Safety of structures can be assured, even if cracks initiate in localized regions of abnormally low toughness, and/or abnormally high stress (LT/HS), if the materials from which they are ...

Abstract: Measurements were made of the full-thickness crack arrest fracture toughness (FTCAT) of three 9-percent Ni steels having the range of thicknesses and Charpy V-notch toughnesses of plates now in ...

Abstract: The data presently available on the plane strain crack arrest toughness (KIa ) of steels are reviewed, using as a definition of KIa the stress intensity factor, K, a short time after a ...
