In recent years the problem of brittle fracture has been one of great importance to fabricators of solid-propellant missile-motor cases, and many tests have been developed to determine the “fracture toughness” of sheet materials as a measure of their resistance to rapid crack propagation (1). After studying many of the tests proposed for the evaluation of fracture toughness, a special ASTM committee recommended the center-notch tension test for the screening of materials in laboratory tests (2).
