Frequency-velocity-wavelength and Rayleigh distance tools
Piezoelectrics, beam profiles, pulse-echo, phased arrays
Snell's law, critical angles, oblique incidence
A-scan, B-scan, C-scan, SAFT, FMC/TFM, TOFD
Curated references from classic NDE texts to recent literature
Each section is built to help you go from first principles to practical lab use.
Wave propagation, acoustic impedance, attenuation, transducer physics, beam forming, imaging modes, and signal processing fundamentals.
Open TheoryInteractive tools: wavelength, near-field distance, attenuation, TOF-to-depth, Snell's law, and acoustic impedance / reflection coefficients.
Open CalculatorsTextbooks, landmark papers, open-source software, simulation tools, and standards (ASTM, ISO) relevant to ultrasonic NDE.
Open ResourcesThis site is an open educational resource compiled from PhD research in ultrasonic NDE at Purdue University. It is designed for graduate students, early-career researchers, and engineers entering the field who need both conceptual grounding and practical tools — in one place.
