Learn how to use wave-based NDT techniques, ultrasonic testing, acoustic emission, etc, to inspect the structural integrity of civil engineering structures, including highways, bridges, dams, and buildings. Wave-based NDT methods allow for reliable and rapid evaluation of civil engineering infrastructure. These methods are particularly useful in long-range inspection; for example, in pipelines, where the wave-based NDT can provide data on hundreds of meters of piping in a matter of seconds.
