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.
