Abstract
The J-integral vs. crack growth resistance curve (J-R curve) is a useful tool for evaluating materials fracture toughness in the ductile region. The widely applied standard for conducting such tests is American Society for Testing Materials (ASTM) Standard E1820-18 [1], in which the normalization analysis method is described in Annex 15. The normalization method requires only load-displacement data and crack size measurements before and after testing, which greatly simplifies the fracture toughness testing and alleviates many issues that arise when testing in extreme conditions.
