ASTM E399-12e2<\/h3>\n

Historical Standard: Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness KIc of Metallic Materials<\/h4>\n
\n

ASTM E399<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1 This test method covers the determination of fracture toughness (KIc<\/sub><\/span>) of metallic materials under predominantly linear-elastic, plane-strain conditions using fatigue precracked specimens having a thickness of 1.6 mm (0.063 in.) or greater2<\/sup><\/span> subjected to slowly, or in special (elective) cases rapidly, increasing crack-displacement force. Details of test apparatus, specimen configuration, and experimental procedure are given in the Annexes.<\/p>\n<\/p><\/div>\n

\n Note 1<\/span>\u2014Plane-strain fracture toughness tests of thinner materials that are sufficiently brittle (see 7.1<\/span>) can be made using other types of specimens (1)<\/span>.3<\/sup><\/span> There is no standard test method for such thin materials.<\/span>\n <\/div>\n
\n

1.2 This test method is divided into two parts. The first part gives general recommendations and requirements for K Ic<\/sub><\/span> testing. The second part consists of Annexes that give specific information on displacement gage and loading fixture design, special requirements for individual specimen configurations, and detailed procedures for fatigue precracking. Additional annexes are provided that give specific procedures for beryllium and rapid-force testing.<\/p>\n<\/p><\/div>\n

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

\n

1.8 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.<\/i><\/p>\n<\/p><\/div>\n
