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.

Aris didn’t understand until the gauntlet showed him. To save Lyra, he wouldn’t fight the Cascade. He would become part of it. The lock required a permanent anchor: his memory of her. Not the photograph. Not the data. The actual, living feeling of being her father. “Then what do you suggest

Inside his lab, the container hissed open. The device was beautiful—a skeletal gauntlet of liquid mercury and crystallized light. Wrapped around its core was a single, faded photograph of a little girl blowing out birthday candles. Lost in the Cascade Incident three years ago

Aris saw Lyra. She was thirty feet away, her hand reaching for a toy she’d dropped. The Cascade’s edge was two seconds from consuming her.

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.
