This article is to evaluation of fracture toughness of carbon steel based on the testing Standards. ASTM Standards ASTM E399-90 “Plane-Strain Fracture Toughness of Metallic Materials”. E1290–70 “Test Method for crack Tip Opening Displacement (CTOD) fracture toughness Measurement”. E1820–80 “Test Method for Measurement of Fracture Toughness”. And British Standard, BS 4762 “Fracture Mechanics Toughness Tests. Method for determination of KIC, critical CTOD and critical J values of metallic materials”. This Standards give a method for determining plane strain fracture toughness values KIC, for carbon steel specimens. The method uses fracture pre-cracked specimens.
