Nondestructive Evaluation (NDE) of Materials Lab

The goal of the Nondestructive Evaluation (NDE) laboratory is to introduce AET students to methods and techniques of NDE of parts and materials. Students learn engineering and physical principles of measurements of sound velocity in different materials, attenuation coefficients, directivity pattern of ultrasonic transducers, and location and dimensions of heterogeneities in various materials, such as holes, cracks, cavities, and flaws. These techniques are studied through experiments that closely simulate industry-relevant manufacturing and testing processes in petrochemical, aerospace, nuclear, railroad, and renewable energy applications using an in-depth case study approach.

The NDE laboratory will serve as a training center for undergraduate AET students, as well as for the workforce of companies, such as Boeing, MISTRAS/CONAM, Lockheed Martin, and PECO Energy. The establishment of a state-of-the art laboratory for NDE purposes allows Drexel and its community-college partners to develop training options for technicians located in the region’s key industries.

NDE curriculum is designed to fulfill Levels I & II NDE in theory and training requirements, according to American Society for Nondestructive Testing (ASNT) Recommended Practice.

Development of this laboratory is supported by the NSF Grant # 0632734 “Implementation of the Internet-Based Nondestructive Evaluation Laboratory for Engineering Technology Curriculum.”
