Nondestructive Evaluation Courses for Undergraduate Engineering and Engineering Technology Students

Two nondestructive evaluation (NDE) laboratory-based courses were developed for Engineering and Engineering Technology (ET) students of Drexel University. The ultrasound NDE laboratory allows for participation in laboratory activities in two modes: the traditional face-to-face classroom mode for students on Drexel’s campus, and a real-time, Internet-based mode for those at remote locations. During the laboratory sessions, students are introduced to tools, methodologies, and techniques utilized by NDE specialists in real-world applications, including calibration and inspection using latest ultrasonic testing instrumentation. The acoustic emission (AE) laboratory procedures are currently developed for face-to-face instruction. Specifically, the course presents principles of AE Nondestructive Evaluation of Materials combining hands-on laboratory experience with lectures. The students learn the physical principles of acoustic emission generation, propagation and detection of acoustical waves in engineering materials and structures, including the underlying science of material deformation, crack growth and failure. Practical applications in various industries are described.
