Many structures, such as aircraft or other lightweight vehicles, are made from thin-ductile structural materials that exhibit low crack-front constraint, which allows for extensive plastic yielding of the material around a crack front. However, many current standards, such as E 399, Test Method for Linear-Elastic Plane-Strain Fracture Toughness K Ic of Metallic Materials, or E 1820, Test Method…
