Abstract
Of the approximately one half million bridges in the United States about 40% are either in need of upgrade or have structural deficiencies [1]. Since it is impractical to replace all deficient bridges, means to quantify their safety and prioritize repairs are needed. Ultrasonic measurements of stress can be useful in evaluation of bridge safety. Here the acoustoelastic effect, (the change in sound speed due to stress) is used.
