Pages: 100 pages

Scope

This standard specifies the test methods for the fracture toughness, crack tip opening displacement, J-integral, and resistance curve of homogeneous metal materials under quasi-static loading. The specimens have notches, and cracks are prefabricated using fatigue methods. The tests are conducted under the condition of slowly increasing the amount of displacement.
