1.1 This test method employs a side-grooved, crack-line-wedge-loaded specimen to obtain a rapid run-arrest segment of flat-tensile separation with a nearly straight crack front. This test method provides a static analysis determination of the stress intensity factor at a short time after crack arrest. The estimate is denoted K<\/i> a<\/i> . When certain size requirements are met, the test result provides an estimate, termed K<\/i> Ia<\/i> , of the plane-strain crack-arrest toughness of the material.<\/p>\n

1.2 The specimen size requirements, discussed later, provide for in-plane dimensions large enough to allow the specimen to be modeled by linear elastic analysis. For conditions of plane-strain, a minimum specimen thickness is also required. Both requirements depend upon the crack arrest toughness and the yield strength of the material. A range of specimen sizes may therefore be needed, as specified in this test method.<\/p>\n

1.3 If the specimen does not exhibit rapid crack propagation and arrest, K<\/i> a<\/i> cannot be determined.<\/p>\n

1.4 The values stated in SI units are to be regarded as the standards. The values given in parentheses are provided for information only.<\/p>\n

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/p>\n
