Application Summary AI generated

This standard specifies the test method for determining the plane-strain fracture toughness (KIC) of metallic materials, which measures a material's resistance to crack propagation under static loading. It is applied in industries such as aerospace, pressure vessel manufacturing, and structural engineering to evaluate the fracture safety of high-strength steels and alloys. The standard is used in quality control and material selection for components where catastrophic failure due to brittle fracture must be prevented.
