Abstract
Objective
This work investigates methods for predicting imminent wire failure during fatigue testing.
Methods
Sensors 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.
Results
Video recording appears to be the most promising of the methods investigated.
Conclusion
It has promise for both single and multi-strand configurations.
Practice
Further investigations could include image/video processing.
Implications
Could 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.
