INCORPORATION OF FRACTURE INFORMATION IN SPECIFICATIONS,

Abstract

The problem of fracture tests is examined for material and process specifications and the use of fracture toughness information is discussed in specifications for hardware acceptance, such as nondestructive inspection specifications. Emphasis is placed on the need to design properly a fracture specimen to achieve maximum use of the information obtained. The use of subsized specimens or qualitative treatment of fracture data simply reduces the ability to effectively apply test data through the design and quality control aspects of the fracture analysis cycle. A simplified analysis is presented to show the predicted effect of crack geometry variations and crack interaction effects on crack size to produce an 'equivalent crack size' effect on fracture strength of a material.
