Hill Engineering has participated in a collaborative, interlaboratory effort to quantify contour method residual stress measurement reproducibility. The study, entitled ‘Interlaboratory Reproducibility of Contour Method Data in a High Strength Aluminum Alloy’ was published through Experimental Mechanics, and is provided open access on Springer Link. The background, objective, and methods from the abstract text are as follows:

When it comes to measuring residual stress in small test specimens, precision is paramount. The slitting method is well suited to this application due to the high accuracy of wire EDM machining. However, this method is not without its challenges, especially when applied to very small test specimens, such as the 0.022-inch diameter wire we recently measured.
