Zusammenfassung:The present invention relates to a jig for a fracture toughness test capable of applying a stable load to a test piece and inducing to occur fracture in a predetermined site, and an apparatus for fracture toughness test using the same. The provided jig for a fracture toughness test comprises: a thread pipe test piece which is formed with a breaking portion and formed with a groove to be inwardly recessed in the circumferential direction; a holder which is formed in a pair to be mounted at both ends of the thread pipe test piece to receive the groove and formed with a through groove having to be inserted with the test piece; a ring member mounted on the groove; and a locking member which is interposed between the ring member and the holder to prevent separation of the ring member.
