ASTM E1820
Full Name
ASTM E1820 – Standard Test Method for Measurement of Fracture Toughness
Scope
This test method covers procedures and guidelines for the determination of fracture toughness of metallic materials using the following parameters: K, J, and CTOD (δ). Toughness can be measured in the R-curve format or as a point value. The fracture toughness determined in accordance with this test method is for the opening mode (Mode I) of loading.
