ASTM E399 EBOOK

ASTM E testing covers the determination of the plane-strain fracture toughness (KIc) of metallic materials by tests using a variety of fatigue-cracked. ASTM E describes the determination of fracture toughness of metallic materials by fatigue tests of precracked specimens. This standard is issued under the fixed designation E; the number 1 This test method is under the jurisdiction of ASTM Committee E08 on Fatigue.
