Hole drilling residual stress measurement method

This week, we have uploaded a new vlog to Hill Engineering’s YouTube channel revolving around a particularly handy residual stress measurement technique. The hole drilling measurement method is one of our most popular residual stress measurement options, and involves the incremental drilling of a small hole into the surface of a specimen. Watch the video below and read on to learn more about the hole drilling method. Continue reading Hole drilling residual stress measurement method

Hill Engineering Vlog: Strain Gaging

Strain gages are key tools when performing residual stress measurements. By tracking the electrical resistance change of the strain gage foil, we can evaluate strain through material deformation. In our vlog presented below, we demonstrate how to apply a strain gage on an aluminum tensile specimen. While the setup described in the video is simple, we are capable of applying strain gages to much more complex geometries to fit the needs of our residual stress tests.
