Description
In this study, a new methodology is developed to detect and monitor preload in wind turbine bolts. The study is part of a larger research project to use the Phased Array Ultrasonic Testing (PAUT) system to robotically test bolt preload. The stress measurement using the ultrasonic method is explained by the acoustoelastic effect, which is based on the sound velocity change in an elastic material subjected to the static stress field.
