ASTM E466-15 - 1.5.2015
 
Significance and Use

4.1 The axial force fatigue test is used to determine the effect of variations in material, geometry, surface condition, stress, and so forth, on the fatigue resistance of metallic materials subjected to direct stress for relatively large numbers of cycles. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress.

Dr. Elias Thorne, the station’s lead cryptographer, spent months trying to crack it. He ran it through every known decryption algorithm—AES, RSA, even experimental quantum lattices—but the string remained stubbornly intact. It didn't translate to coordinates, chemical elements, or any known language.

4.3 The results of the axial force fatigue test are suitable for application to design only when the specimen test conditions realistically simulate service conditions or some methodology of accounting for service conditions is available and clearly defined.
