Book excerpt: High-strength ferrous and titanium alloys are of interest for use in complex structures; a knowledge of the notch fracture toughness of these alloys is necessary to preclude catastrophic failure. A previously established relationship between the dynamic tear test energy and the explosion tear test performance provides reliable fracture-toughness information of those alloys characterized by a toughness level requiring plastic deformation to propagate fracture. This analysis has not been extended to the ultrahigh-strength alloys in which fracture can propagate castastrophically at elastic stress levels. For these alloys, the analytical methods of linear elastic fracture mechanics provide the required elastic stress level and flaw-size relationship for fracture. This report deals with a 'marriage' of the two approaches-the engineering and the analytical-by correlative techniques. (Author).
