About this course

Skip About this course

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.

In this course, students will learn about wave-based NDT methods, including ultrasonic inspection, acoustic emission, resonant frequency testing, and electromechanical impedance testing. The topics include piezoelectric effect, basic principles of various wave-based NDT methods, and their associated data acquisition.

The course also includes case studies so students can apply the knowledge to field inspection or monitoring of materials and structures.
