標準簡介
CONTAINED IN VOL: 03.01 Determines JIC, which can be used as an engineering estimate of fracture toughness near the initiation of slow stable crack growth for metallic materials. Applies specifically to geometrics that contain notches and flaws and that are sharpened with fatigue cracks. The specimens recommended are generally bend type that contain deep initial cracks. The loading rate is slow and environmentally assisted cracking is assumed to be negligible.
