Abstract:

Dynamic Tear DT test R-curves were developed to define the inherent resistance of structural materials to fracture in terms of the energy-per-unit extension required to cause rapid crack extension. Translation of the R-curve characterizations to useful form for design of structures to preclude fracture has been accomplished by the use of Ratio Analysis Diagram RAD. R-curve concepts and RADs have been established for steels, aluminum alloys, and titanium alloys. Author Modified Abstract
