Revision of E1457-19e1 Standard Test Method for Measurement of Creep Crack Growth Times in Metals


E1457 (no change)
crack size, a [L]—principal lineal dimension used in the calculation of fracture mechanics parameters for through thickness cracks as defined in the applicable standard. Discussion—In practice, the value of a is obtained from procedures for measurement of physical crack size, ap, original crack size, ao, and effective crack size, ae, as appropriate to the situation being considered. Discussion—In this test method, the physical crack size is represented as ap. The subscript, p, is everywhere implied.
