Abstract

An instrument called the ultrasonic extensometer is used to measure tensile preload in bolts used in structural joints. The instrument can also be used to measure bending in bolts used in shear joints. The bolt bending creates a bending stress in the bolt. The bending stress causes the ultrasonic beam to bend slightly. The paper develops theory governing the path of ultrasonic beam passing through the bending stress field. The theoretical differential equations are solved to provide a numerical solution to trace the path of ultrasonic beam. A numerical example is provided to illustrate the solution. In addition, the paper discusses the effect of beam bending on the ultrasonic measurement of bending loads on a bolt.
