Description
Brandon Mills, Yashar Javadi, and Charles N Macleod present a 2026 study on a hidden error source in ultrasound stress sensing: the coupling gel layer between probe and metal. Their phased-array method times a surface-skimming wave to infer leftover stress after welding or printing. Gel thickness shifts that timing, and the team modeled the bias, measured it on the bench, and built a correction workflow.
Left alone, gel variation faked stress errors of about 36 megapascals, a real bite of a part's strength. The model-guided fix cut the timing bias nearly to zero in tests, shrinking stress error to about one megapascal. The authors give calibration and uncertainty guidance toward field use of the sensor on welds and printed parts.
