Recent Advancements in the Hole-Drilling Strain Gauge Residual Stress Method

The hole-drilling strain-gage method is a cost-effective technique for residual stress measurements on different materials. The method is codified at world level by the ASTM E837-13 standard.

This webinar will introduce some recent and advanced techniques that can extend the method to non-standard applications; furthermore, these techniques can also guarantee a better accuracy in the stress calculation. Moreover, the introduction of a new approach for the evaluation of uncertainty offers an all-round solution for the entire measurement process.

Short overview of a typical residual stress measurement by mechanical methods
Recent upgrades to increase the fields of application of the hole drilling technique
Main sources of uncertainty of the method
Typical residual stress calculation and results
