Abstract
ObjectiveThis work investigates methods for predicting imminent wire failure during fatigue testing. MethodsSensors that measure changes in vibration, displacement, and infrared signatures were explored, and in-situ video recording was studied for its ability to capture changes in the shape of the wire. ResultsVideo recording appears to be the most promising of the methods investigated. ConclusionIt has promise for both single and multi-strand configurations. PracticeFurther investigations could include image/video processing. ImplicationsCould be used to determine if the number of fatigue cycles to complete fracture is an accurate measure of the fatigue life of multi-stranded wire.
