Data produced from the use of a proposed new ASTM International standard will be employed in the design of new, more efficient aircraft engines as well as for piping, steam and gas turbines used in power generation. The proposed new standard, WK21984 , Test Method for Creep-Fatigue Crack Growth Rate Testing, is being developed by Subcommittee E08.06 on Crack Growth Behavior, part of ASTM…

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…
