Abstract:

The fracture resistance characterization information obtained from the Dynamic Tear and K sub Ic test methods for high- and ultrahigh-strength aluminum and titanium alloys is summarized. These tests have been used to establish the fracture resistance characterizations for these materials covering a wide range of yield strength and metallurgical conditions. Ratio Analysis Diagram procedures have been evolved for translating this information into structural mechanics predictions for fracture. The general physical metallurgical characteristics for the generic families of these materials are discussed in relation to their potentials for optimizing aluminum and titanium alloys to high levels of fracture resistance.
